Jose Luis López commented on HDFS-17951:
----------------------------------------
[~fuchaohong] Please assign this to me. I started working on this and also a
review of how the Miniclusters are shutdown in the tests, see related issue.
They are both related. Under load, the method returns less than the maximum
numbers of threads configured pool size.
> TestFsVolumeList#testAddRplicaProcessorForAddingReplicaInMap fails.
