Jason Lowe commented on HADOOP-12706:
-------------------------------------
I can reproduce it fairly quickly by simply running mvn surefire:test
-Dtest=TestLocalFsFCStatistics in a loop within the hadoop-common directory.
The system is not heavily loaded when the test runs, so I'm wondering if adding
more time is going to help or just have the test take longer. I tried
increasing the wait duration from 10 seconds to 30 seconds, and it still can
fail. I'll try to dig into this more tomorrow to see why the references aren't
getting cleaned up when it fails.

> TestLocalFsFCStatistics has been failing sometimes, and when it fails it
> appears to be from FCStatisticsBaseTest.testStatisticsThreadLocalDataCleanUp.
> The test is timing out when it fails.
