Akira AJISAKA commented on HADOOP-12588:
----------------------------------------
+1, thanks Masatake.
* I'm thinking the visibility looks to be the cause because there are no other
reason to fail the test. (I couldn't reproduce the error locally, so I couldn't
confirmed that the visibility is the real cause.)
* The patch is safe to apply.
* The test failures are unrelated because the patch changes TestGangliaMetrics
only.
> Fix intermittent test failure of TestGangliaMetrics
