Surendra Singh Lilhore commented on HDFS-12556:
-----------------------------------------------
Attached v2 patch. This patch fixing two test case.
# TestPersistentStoragePolicySatisfier#testWithRestarts()
# TestPersistentStoragePolicySatisfier#testWithCheckpoint()
First test is failing because of {{ArrayIndexOutOfBoundsException}} and it is
coming because block analysis is done without read lock. Second test is failing
because first test case. First test case timed out without waiting to shutdown
the cluster. This is cause the inconsistency in namedir for second test case.
> [SPS] : Block movement analysis should be done in read lock.
