Arpit Agarwal commented on HDFS-5527:
-------------------------------------

Looks like an NN bug. From the [Jenkins logs|https://builds.apache.org/job/PreCommit-HDFS-Build/5488//testReport/org.apache.hadoop.hdfs.server.blockmanagement/TestUnderReplicatedBlocks/testSetrepIncWithUnderReplicatedBlocks/].

{code}
2013-11-19 19:09:03,406 INFO  BlockStateChange (BlockManager.java:computeReplicationWorkForBlocks(1366))
- BLOCK* ask 127.0.0.1:59892 to replicate blk_1073741825_1001 to datanode(s) 127.0.0.1:38708
