Incorrect check and message in FsDatasetImpl#invalidate

    Details

    • Type: Bug
    • Status: Resolved
    • Priority: Major
    • Resolution: Fixed
    • Affects Version/s: None
    • Fix Version/s: 2.8.0, 3.0.0-alpha2
    • Component/s: datanode
    • Labels:
      None
    • Release Note:
      Improves the error message when datanode removes a replica which is not found.

      Description

      The following error check and message is incorrect, because info is null if (1) the block id does not exist in ReplicaMap or (2) the generation stamp of block does not match the replica entry in ReplicaMap.

      FsDatasetImpl#invalidate
             final ReplicaInfo info = volumeMap.get(bpid, invalidBlks[i]);
              if (info == null) {
                // It is okay if the block is not found -- it may be deleted earlier.
                LOG.info("Failed to delete replica " + invalidBlks[i]
                    + ": ReplicaInfo not found.");
                continue;
              }
              if (info.getGenerationStamp() != invalidBlks[i].getGenerationStamp()) {
                errors.add("Failed to delete replica " + invalidBlks[i]
                    + ": GenerationStamp not matched, info=" + info);
                continue;
              }

        This issue will be happened when we use the method ReplicaMap#get(String bpid, Block block) rather than ReplicaMap#get(String bpid, long blockId). In the former mehtod, the method returns null not always indicates that the replica is not existed since it wll also do a generation stmap match.

        I make a code glance in FSDatasetImpl, I found the method FSDatasetImpl#getReplicaInfo also have the similar problem. I also make a fix in my patch. Attach a initial patch to make a minor change.

        Hi Yiqun Lin thanks for your patch. I think it generally looks good to me.
        One nit:

                        + ": GenerationStamp not matched, info=" + infoByBlockId);
        

        Instead of printing the whole ReplicaInfo which we do not need,
        (it looks like this, if you are curious)

        FinalizedReplica, blk_1073803461_74266, FINALIZED
          getNumBytes()     = 54739015
          getBytesOnDisk()  = 54739015
          getVisibleLength()= 54739015
          getVolume()       = /data/4/dfs/dn/current
          getBlockFile()    = /data/4/dfs/dn/current/BP-1092022411-10.0.0.55-1474407949037/current/finalized/subdir0/subdir240/blk_1073803461
        

        I think we just need to print the block:

        so probably Block.toString(infoByBlockId)

        Also, instead of printing "info=", use more self explanatory message, like "existing replica is "
        What do you think?

        Thanks Wei-Chiu Chuang for the review. One point that I want to say, the test TestDiskspaceQuotaUpdate fails in this JIRA. I found the reason is that there is some bind exception. I have filed the JIRA HDFS-11025 to make a quick fix. We have reach an agreement that back up on different port across restarting datanode will not influce the current logic. So I have one proposal that you can also make a commit for that after you have looked into for that, . Thanks.

        Committed this to trunk. I'll commit this to branch-2 and branch-2.8 later.
