      Description

      When a NodeManager's local disk gets almost full, the NodeManager sends a health report to ResourceManager that "local/log dir is bad" and the message is displayed on ResourceManager Web UI. It's difficult for users to detect why the dir is bad.

        Attaching a patch to add a new public method getDisksHealthReport(boolean, boolean), and deprecate the existing method getDisksHealthReport(boolean) for backward compatibility. I'll attach a screen shot later.

        I reconsidered that, after all the issue is not a problem because

        • Admin can read NodeManager's log and find the message as follows:
          2015-02-26 07:34:22,485 WARN org.apache.hadoop.yarn.server.nodemanager.Directory
          Collection: Directory /usr/local/20150225-YARN-3254-2/logs/userlogs error, used 
          space above threshold of 90.0%, removing from list of valid directories
          
        • This patch is still incompatible as jmx information is actually changed.

        Akira Ajisaka Although the Nodemanager's log shows the reason for directories being unhealthy, it would be useful to have the NodeManager's UI health report display if the directories have errors/are full. Would you mind if I take over this JIRA if you are not working on this currently ? Also, can you please explain why the patch is incompatible with jmx information being changed ?

        No. You can take it over.

        Also, can you please explain why the patch is incompatible with jmx information being changed ?

        This health report is obtained from jmx. Accoding to the documentation (https://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/Compatibility.html#MetricsJMX), changing the jmx information breaks compatibility. Now I'm thinking you can add the message to the Web UI if you create an additional jmx information and use it.

        Akira Ajisaka,

        I think the original definition of JMX metrics compatibility is overkill, I can understand the "semantic consistency" part, for example, change unit (from GB to MB, etc.). For text fields such as report, we should be able to change them if needed.

        For example, YARN-90/YARN-6302 have already changed report field, if we strictly follow the rule, we probably need to revert these patches as well.

        I would prefer to continue improving the text field. And start discussion to modify the compatibility rule.

        cc: Karthik Kambatla (original author of the compatibility doc) and Daniel Templeton.

        Thanks Suma Shivaprasad
        Generally patch looks fine. Few minor comments.

        1. I think DirectoryCollection#getErroredDirs is a public api. Could u please mark as evolving and some more information in api. I think existing java doc is not that great there. However its better we do that.
        2. fullLocalDirsList could be renamed as diskFullLocalDirsList or some better name similar for logdirs as well.

        What does "full" mean?

        • out of inodes?
        • out of space?
        • out of writable space? (eg, root reserved space can't be written to)
        • out of quota? (eg, zfs set quota=foo)
          ....

        In DirectoryCollection.isDiskUsageOverPercentageLimit(), we use File#getUsableSpace and File#getTotalSpace to get a disk usage information and mark disks as FULL if used size is over a threshold. So its mostly about disk space related for now.

        In latest patch, new variables are renamed to diskFullLocalDirsList etc.

        I think we need to clearly mention that in the jmx info: usable space is below some percentage or no more usable space.

        Updated the patch to display the exact root cause for the disk error/capacity exceeded cases. These error diagnostics were already available in DirectoryCollection earlier but was ignored and not surfaced in the health report. Along with the ratio of disks marked as unhealthy for local/log dirs, the reason why each of them was marked unhealthy will be surfaced in health report. Sample errors below

        1/1 local-dirs have errors: [ /invalidDir1 : Cannot create directory: /invalidDir1 ] 1/1 log-dirs usable space is below configured utilization percentage/no more usable space [ /hadoop-3.0.0-beta1-SNAPSHOT/logs/userlogs : used space above threshold of 1.0% ]

        Thanks Suma Shivaprasad

        Some more comments

        1. unused import java.util.NoSuchElementException
        2. Java doc could also add param info as we ill new apis such as DirectoryCollection#getDirectoryErrorInfo etc
        3. Its better to use errorInformation instead of getValue.
          directoryErrorInfo.put(entry.getKey(), entry.getValue());
          
        4. Could below message be kept at class level in LocalDirsHandlerService
          final String diskCapacityExceededErrorMsg
          
        5. One doubt in DirectoryCollection.checkDirs()
          As per latest patch, directoryErrorInfo is the super set which contains dirs from errorDirs, fullDirs and nothing more.
          Now while buildDiskErrorReport call, directoryCollection.isDiskUnHealthy is invoked for erroredLocal/LogDirsList and diskFullLocal/LogDirsList. I think this is not needed as contents from errorDirs and fillDirs are in that map for sure. In that case, could we skip this check and remove that api. Please correct me if I missed something here.

        -->Thanks for catching this. There was one case where the errorDirs was being updated but directoryErrorInfo was not being updated i.e in createNonExistentDirs which caused the lookup to return null. Have fixed that as part of the updated patch. Not sure if any other cases exist. Hence added a check to just be safe with the error information retrieval.
