---------------------------------------
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:
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.
