             Summary: cfhistograms dtest flaps on trunk and 2.2
                 Key: CASSANDRA-9741
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-9741
             Project: Cassandra
          Issue Type: Bug
            Reporter: Jim Witschey
             Fix For: 2.2.x, 3.0.x


{{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:

I haven't seen it fail locally yet, but haven't run the test more than a couple times because it takes a while.
