> {{jmx_test.py:TestJMX.cfhistograms_test}} flaps on CassCI under trunk and 2.2.
> On 2.2, it fails one of its assertions when {{'Unable to compute when histogram overflowed'}} is found in the output of {{nodetool cfhistograms}}. Here's the failure history for 2.2:
> http://cassci.datastax.com/view/cassandra-2.2/job/cassandra-2.2_dtest/lastCompletedBuild/testReport/junit/jmx_test/TestJMX/cfhistograms_test/history/
> On trunk, it fails when an error about a {{WriteFailureException}} during hinted handoff is found in the C* logs after the tests run ([example cassci output|http://cassci.datastax.com/view/trunk/job/trunk_dtest/315/testReport/junit/jmx_test/TestJMX/cfhistograms_test/]). Here's the failure history for trunk:
> http://cassci.datastax.com/view/trunk/job/trunk_dtest/lastCompletedBuild/testReport/junit/jmx_test/TestJMX/cfhistograms_test/history/
> I haven't seen it fail locally yet, but haven't run the test more than a couple times because it takes a while.
