Kihwal Lee commented on HDFS-2881:
----------------------------------
It failed in one of the precommit builds. It looks different this time.
https://builds.apache.org/job/PreCommit-HDFS-Build/2683//testReport/
While waiting for the two bad replicas, the blocks were fixed. So
waitCorruptReplicas() only saw < 2 in each loop. Moreover, the first corrupt
block was reported by DFSClient while this method was reading the file and got
fixed (rereplicate/invalidate) before it looped, without involving
BlockScanner.
