> TestBalancer failing intermittently because of not reseting

> Project: Hadoop HDFS
> Issue Type: Bug
> Components: test
> Affects Versions: 3.0.0
> Reporter: Lin Yiqun
> Assignee: Lin Yiqun
> Attachments: HDFS-10336.001.patch
>
>
> The unit test {{TestBalancer}} failed sometimes.
> I looked for the reason. I found two main reasons causing this.
> * 1st. The test {{TestBalancer#testBalancerWithKeytabs}} executed timeout.
> {code}
> org.apache.hadoop.hdfs.server.balancer.TestBalancer
> testBalancerWithKeytabs(org.apache.hadoop.hdfs.server.balancer.TestBalancer)
> Time elapsed: 300.41 sec <<< ERROR!
> java.lang.Exception: test timed out after 300000 milliseconds
> at java.lang.Thread.sleep(Native Method)
> at
> org.apache.hadoop.hdfs.server.balancer.Dispatcher.waitForMoveCompletion(Dispatcher.java:1122)
> at
> org.apache.hadoop.hdfs.server.balancer.Dispatcher.dispatchBlockMoves(Dispatcher.java:1096)
> at

> at
> org.apache.hadoop.hdfs.server.balancer.TestBalancer.access$000(TestBalancer.java:125)
> {code}
> * 2nd. The test {{TestBalancer#testBalancerWithKeytabs}} reset the {{UGI}}
> not completely sometimes in the finally block. And this affected the other
> unit tests threw {{IOException}}, like this:
> {code}
> testBalancerWithNonZeroThreadsForMove(org.apache.hadoop.hdfs.server.balancer.TestBalancer)
> Time elapsed: 0 sec <<< ERROR!
> java.io.IOException: Running in secure mode, but config doesn't have a keytab
> at org.apache.hadoop.security.SecurityUtil.login(SecurityUtil.java:300)
> {code}
> And there were not only one test will be affected by this. We should add a
> line to do before doing reset {{UGI}} operation and can avoid the potenial
> exception happens.
> {code}
> UserGroupInformation.reset();
> {code}
