        There are various steps one can take to improve the availability of the HDFS Namenode (NN) including reducing startup time, refreshing configuration without restarting the cluster, reducing upgrade time, and providing an manual or automatic failover of the NN, etc. This jira focuses on failover of the NN to address the issue of NN as a single point of failure.

        There are various ways to provide failure of NN. Some of these include the use of shared storage while others do not. Some include the use of IP failover while others use a smart client side library. One could use Zookeeper for leader election or some other off the shelf scheme such as Linux HA. These different solutions can share some framework components as building blocks. The purpose of this jira is to define these framework components for building failover solution towards improving availability. The avatar node could use some of these framework components. Some of the code from avatar node can be used towards building the framework components.

        Sub jiras will be created to address each of the framework components.

        I assume that in what is envisioned, the code running on active and standby will be identical, with the only difference being whether an active switch is enabled.

        It would be good if the code for active/standby detection was pluggable. So that different options for failover could be provided. It wouldn't be good to require that a zookeeper ensemble be set up just to run a namenode.

        How does heartbeat deal with network partition? My understanding of it is that it sends packets at intervals to the other node, and if they don't get through it considers the other dead. This could create a situation where both active and standby think that the other is dead, and both become active, leading to divergent filesystem states on each machine.

        If you want manual failover, from the server perspective you need to do nothing. Operators can have 2 namenode machines, with the namenode only running on one, writing to shared storage.

        Yes. Active/standby will be the state of the namenode and code should be identical.

        The document does not state zookeeper is needed. HA solution requires a quorum service, that should be pluggable. ZK is one of the options.

        Why do you need more than 2 NNs? Having more than 2NNs could solve need for outside quorum service. But number of NNs could be huge, especially in federated clusters.

        Its mentioned as "Out of scope" but having read operations on a standby could be a use case for this. Read throughput could be increased by adding more standby nodes. While this is out of scope, it would be good to keep it in mind now so that the design doesn't end up being tied to just 2 nodes which may be hard to rectify later.

        Hey Sanjay, Suresh,

        Read through the doc, here are some comments/questions I've been meaning to post. Also, I've attached a doc that Todd, atm, and I wrote so we can compare notes.

        Overall, looks great, I agree with the scope.

        Agree with failures supported, you mean simultaneous failures right? We should list these failures out. Eg the NN today can cope with multiple disk failures but not a single failed dimm.

        How does NN fail-over impact federation? Eg does viewfs have any special requirements as a client?

        Agree that short GC pauses should not be considered failures, and the corrolary that long GC pauses should. This only works well if GC on the standby is not correlated with GC on the active NN (othewise you fail over to standby just to have it GC). How can we ensure this is the case? Perhaps force regular GC's on the standby?

        Wrt requirement #2, I assume fail over to new version of HDFS (ie having different versions of HDF interoperate) is out of scope for this framework. However fail-over to a minimally patched NN (ie no protocol, wire-level format changes) should work.

        Wrt requirement #4, this means all state changes need to be made persistently off-host before success is reported to clients.

        > How does NN fail-over impact federation? Eg does viewfs have any special requirements as a client?
        In case of federation, each NN needs its own warm or hot failover. Cannot do N+k failover because of the large memory requirements for a NN unless one wants to limit it to cold failover.

        Viewfs is separate layer and not required for federation; one could choose to use symbolic links or one could choose to not provide a global namespace. But if one were to use viewfs, I am not aware of any additional failover issues.
        Viewfs has bindings like: /user ->hdfs://nnOfUser/
        The failover issues are the same as if hdfs://nnofUser was your default file system.

        For failover during upgrades, the DNs need to be able to communicate to both versions of the NN. This is true for dot releases and will only be true if we support rolling upgrades. I will clarify this on the next version of the document.

        Thanks for incorporating the feedback. New doc looks good. Some comments:

        • Section 8.1 - I think the BN approach is to run multiple BNs, this way the 3f use case is not a problem as long as you have at least one BN alive, and you don't need shared storage to address 3f. This is similar to GFS' multiple shadow masters.
        • Section 8.3 - fail-over time doesn't need to be longer if the client is notified when there's a new primary. One idea, clients could watch an ephemeral ZK node, though there's an open question as to whether ZK can support as many observers as we have clients.
        • Section 8.5 - We need to figure out where the FailoverController (FC) runs, if lives in the same failure domain as the primary then you've still got a single point of failure. If it lives on a different failure domain then it may not be able to tell if the primary has failed, or be able to take the appropriate action if it has (eg due to lack of connectivity). Obviously the FC needs to be HA itself too (eg leader elected, new FC is spawned if the primary FC fails).
        • Section 9.9.1 - Todd and I have investigated fencing in NFS some. In v3 locking (NLM) doesn't work because dead clients maintain the lock. We'll need to have a pluggable shell command (eg some vendors provide a perl module that can ssh in and fence a particular IP) if we don't want to require IPMI, ILO, etc for stonith.

        in the design docs, why is "fencing" needed?
        if the namenode uses ZK for leader election, it needs to have a Watcher on the ephemeral node, if the namenode loses its leader status, the Watcher should return "disconnect" or "node removed" event, so that the namenode can naturally shutdown itself. doesn't this achieve what is mentioned in the "fencing" paragraph?

        The problem isn't on the Zookeeper side, really.

        The problem is that you have to be able to detect failures quickly, but not capriciously. Pretty much the only valid way to do this is with heartbeats of some kind which means that the time between heartbeats is the shortest response time possible. Moreover, the monitored program has to be sure that it can meet the real-time constraint imposed by the heartbeat rate. With the NameNode and possible GC, this is really, really hard to do for short heartbeats periods.

        There is perhaps some mileage to be had to synchronizing any fencing with the heartbeat so that you at least get rid of that uncertainty.

        Overall, this is a hard problem which is the reason for protocols like two-phase commit.

        The problem is not with the timing of delivery of disconnect event. During fail over, the standby taking over as active may not be able to communicate with previous active (directly/indirectly) to assert that the previous active has relinquished the role of active. This could be due to network partition, active not functional due to GC, OS issues etc. In such a scenario, the only way for new active to ensure shared resource is not controlled by two actives is to fence the shared resource.

        Hi Yang, The zk heartbeats and delivery of notifications is not inline with the HDFS writes to its transaction logs. Assume a scenario where ZK delivers a disconnected event to NameNode, but the NameNode already is in the midst of a flushing a long list of transactions to its transaction logs. This could potentially take a non-trivial amount of time (process scheduling, GC issues, etc).

        Todd: what is our proposed solution for doing IO fencing on transaction logs that reside on a NFS filer? Here we are proposing that we do the following before we can do an auto failover:

        1. If the original NameNode is reachable, kill the original NameNode process and verify that it is killed.
        2. If step 1 fails (because of network connectivity issue), then issue a power-cycle event to the original NameNode machine via its configured console port. Verify that machine is power-cycled.
        3. If Step 2 fails, then abort auto failover. Otherwise continue failover sequence.

        The discussion in HDFS-1108 revealed that Todd, Suresh and Eli (and probably others) are building HA approach based on shared storage (NFS filers) journal synchronization. The motivation for this is claimed to be the simplicity of the approach, compared to the direct streaming of edits to the StandbyNode. I think there are 2 main questions that need to be addressed with respect to this:

        1. Why do you introduce a dependency on enterprise hardware when you run a commodity hardware cluster?
          People running a 20-node Hadoop cluster will have to spend probably the same amount extra on a filer.
        2. How do you address the race condition between NN addBlock and DN blockReceived?
          Explanation: When HDFS client needs to creates a new block it sends addBlock() command to the NameNode. NN (assuming HDFS-1108 is fixed) writes addBlock transaction to the shared storage. The client writes data to the allocated DataNodes. Each DataNode confirms that it got the replica by sending blockReceived() message to NN and SBN. If blockReceived() is sent to StandbyNode before it consumed addBlock() transaction for this block from shared storage, blockReceived() will be rejected since SBN still does not know the block exists. SBN will eventually learn about that same replica from the next block report, but this can be one hour later.
          SBN will be one hour behind the active NN, which is not hot.

        Hi Konstantin,

        HDFS-1975 (sharing the namenode state from active to standby) was created back in May and the description clearly states that the "proposed solution in this jira is to use shared storage". It's probably the most appropriate place for this discussion.

        Thanks,

        @Konstantin,
        I posted the second scenario in HDFS-1971 before (With out HDFS-1108).

        below is the Sanjay's reply.

        However your scenario is a good one: a standby processing BRs from DNs and edits from Active NN may get them out of order.
        This scenario applies to HDFS-9175 that reads from a shared editsLog file system and also for Backup NN.

        Is this is the scenario/similar you are asking?
        Please correct me if i understood wrongly.

        Pretty good unit test coverage. Liked the idea of testing failover under mixed load of SLive, Terasort, etc. Good plan for testing HBase survival after NN failover.
        One suggestion: we should test failover during upgrade. We don't want anybody doing it, but somebody will anyway. I see section on testing upgrade in Hari's document, could you please add failover in the middle.

        Good point about upgrade failover. I think for the first cut we should disallow the NN to start with HA enabled if the upgrade flag is passed, or if there is a pending unfinalized upgrade. Then we can circle back on this as an improvement. Does that seem reasonable?

        Regarding DFSIO: So far we are doing cluster testing on ~100 node clusters here at Cloudera. If you can recommend a good DFSIO setting we'll be sure to try it (and also try with reduced block size to increase the block-related load on the NN and DNs)

        1. 5 nodes in total: 2 namenodes(non-HA config uses just one) and 3 datanodes.
        2. The edits log is NFS mounted for both HA and non HA setup
        3. TestDFSIO is started on one datanode. Resource manager and nodemanager are also on the same datanode.

        Using TestDFSIO write/read 10 files with filesize as 1MB

        I'd recommend 2 series of DFSIO consisting of -write -read and -append in each series and -fileSize = 1 to 10GB. Pick one value for all runs. We want files with multiple blocks.
        Series 1. -nrFiles = 95
        Series 2. -nrFiles = 95*4
        I chose 95, which is a bit less than # of nodes (100).
        And 95*4 - intended to spin 4 drives on most of the nodes if you have 4 drives or more.
        Don't forget to turn off speculation.
        And please watch std deviation in the results.
        In my experience Throughput values don't make sense if std deviation is high.

        For anyone else who wants to review it, note that we've been merging from trunk -> HA branch almost daily, so just looking at a diff between trunk and the HA branch should mostly highlight the salient changes for HA. I also strongly recommend that any reviewers who are just now looking at the branch take a look at the testing plan document attached to this JIRA by Todd, which discusses which areas of the code have the most changes in section 1.5.

        I've completed a round of preliminary performance testing on a 100-node cluster, each with 48G RAM, gigabit ethernet, 6 disks, dual quad core with hyperthreading.

        The three builds were trunk (rev 5b8bdf3c11fc69a9076e2b1e3385ecd179975c7d), HA branch (tip), and the same HA branch but with HA turned off.

        The HA NN is configured to log to an NFS mount, which unfortunately is just a normal Linux NFS box in this case, in the same rack. It was also unfortunately running a DN, though I didn't realize it until I was halfway through the benchmarks, and didn't want to start over from scratch.

        I ran the TestDFSIO benchmarks as suggested by Konstantin, first with 95 files and then with 380 files. Each file is 5GB. I will attach the results as a TSV file momentarily. The overall summary is that there seems to be a ~4% hit for turning on HA for the write benchmark. The read benchmark has too high variability to really be sure. Even the write one doesn't seem that consistent, given that the HA branch, when HA was disabled, actually went some 2.5% faster than trunk. (these numbers from the 380-file case)

        I also ran teragen in two different scenarios. The first scenario is a realistic workload (256M blocks):

        Build Runtime Slot time
        HA On 8m5s 3682m
        HA Off 8m12s 3756m
        Trunk 7m10s 3163m

        Here there seems to be a bad performance degredation from the HA branch (about 20%).

        The second workload was to try to stress the system by setting block size to 4MB (resulting in ~800-1000 block allocations/second):

        Build Runtime Slot time Edit log size
        HA On 12m24s 6655m 1.2GB
        HA Off 8m40s 4469m 1.2GB
        Trunk 7m4s 3375m 6.2MB

        Note here the much bigger degredation. I also included the size of the edit logs in this later benchmark.

        I'm pretty confident from looking at jstacks while this was running that the bad performance is due to the new "persistBlocks" calls done in the HA branch. We used to be sloppy about persisting blocks, whereas now we actually write down all of the block allocations as they proceed. The 4MB block case was much worse, since each file being written by teragen consisted of 423 blocks. The persist blocks calls towards the end of the file were logging several KB worth of data, and this resulted in a very large edit log as you can see in the table above. The difference between HA-on and HA-off is that the HA-on mode actually fsyncs all of these block allocations.

        So before we merge I think we should do a bit of optimization in this area. I will file a JIRA this evening or tomorrow with a couple of easy wins.

        I ran a t-test which says that the difference in means isn't statistically significant. I'm also running the 256M-block teragen just to be safe. It's not complete yet but so far the results look good.

        The optimizations also reduced the edit log size for the 4MB-block by a factor of two.

        So I think once these above JIRAs are committed, we should be fine to merge to trunk. I'll also continue to work on the performance with HA on, but the important issue for merge is to make sure we don't regress the non-HA case.
