Colin Patrick McCabe commented on HADOOP-12706:
-----------------------------------------------
Thanks for the patch, [~sjlee0]. I agree that it seems a bit iffy to rely on
{{System.gc}}, but I'm not sure if we have any other choice. The behavior we
are testing is gc-related, after all.
The patch looks good, but I wonder if we could make it simpler by avoiding
adding the "for" loop. I posted HADOOP-12706.002.patch which implements
this-- let me know what you think.
I have been running this in a loop for a half hour and so far have seen no
failures.

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