Aaron T. Myers updated HDFS-4261:
---------------------------------
Attachment: test-balancer-with-node-group-timeout.txt
I just looped all of the balancer tests on my machine for an hour and a half
and did end up with one timeout in TestBalancerWithNodeGroup. I'm attaching the
thread dump to this JIRA.
Despite this, I think we should probably go ahead and commit this patch and
file a new JIRA for this intermittent failure. This latest patch definitely
fixes a few issues in the balancer, improves the balancer tests, and makes the
tests fail much less frequently.
Unless anyone objects, I'll commit this patch later today and file a new JIRA
for the intermittent failure.

> 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.
