Chris Nauroth updated HDFS-4261:

Attachment:
org.apache.hadoop.hdfs.server.balancer.TestBalancerWithNodeGroup-output.txt.win

jstack-mac-18567
I'm attaching multiple files.
There are thread dumps from 2 separate runs that timed out with the v6 patch,
one on Mac and one on Windows. Both thread dumps show the same thing: stuck in
{{Balancer#waitForMoveCompletion}} waiting for the pending queue to reach
empty. Perhaps there is a race condition preventing the queue from getting
drained?
I've also attached the log output from each test run.

> When I manually ran TestBalancerWithNodeGroup, it always timed out in my
> machine. Looking at the Jerkins report [build
> #3573|https://builds.apache.org/job/PreCommit-HDFS-Build/3573//testReport/org.apache.hadoop.hdfs.server.balancer/],
> TestBalancerWithNodeGroup somehow was skipped so that the problem was not
> detected.
