Date Wed, 19 Apr 2017 00:26:42 GMT
Andrew Wang created HDFS-11672:
----------------------------------

             Summary: Fix some misleading log messages related to EC block groups
                 Key: HDFS-11672
                 URL: https://issues.apache.org/jira/browse/HDFS-11672
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: erasure-coding
    Affects Versions: 3.0.0-alpha1
            Reporter: Andrew Wang
            Priority: Minor


I turned the NameNode's BlockStateChange and hdfs.StateChange logs up to debug, noticed some
out of date log messages like the following:

{noformat}
2017-04-18 17:19:50,639 [IPC Server handler 4 on 45133] DEBUG hdfs.StateChange (FSDirWriteFileOp.java:addBlock(507))
- DIR* FSDirectory.addBlock: /test2RecoveryTasksForSameBlockGroup with blk_-9223372036854775792_1001
block is added to the in-memory file system

2017-04-18 17:19:50,836 [Block report processor] DEBUG BlockStateChange (LowRedundancyBlocks.java:update(353))
- BLOCK* NameSystem.LowRedundancyBlock.update: blk_-9223372036854775792_1001 has only 8 replicas
and needs 9 replicas so is added to neededReconstructions at priority level 2

2017-04-18 17:19:51,235 [IPC Server handler 4 on 45133] DEBUG hdfs.StateChange (FSNamesystem.java:closeFile(3740))
- closeFile: /test2RecoveryTasksForSameBlockGroup with 1 blocks is persisted to the file system
{noformat}
