> URL: https://issues.apache.org/jira/browse/CASSANDRA-14158
> Project: Cassandra
> Issue Type: Bug
> Components: Testing
> Reporter: Michael Kjellman
> Assignee: Marcus Eriksson
> Priority: Major
>
> repair_test.py::test_dead_coordinator is flaky due to occasionally failing
> when a JMX connection error is propagated by nodetool.
> the test has failed 4+ times for the same reason.
> latest failure can be found in the artifacts for the following circleci run:
> [https://circleci.com/gh/mkjellman/cassandra/538]
> I *think* that this might be expected behavior for this test and we just need
> to catch any ToolError exceptions thrown and only fail if included stack is
> for any error other than "JMX connection closed."
> {code}
> stderr: error: [2018-01-10 07:07:55,178] JMX connection closed. You should
> check server log for repair status of keyspace system_traces(Subsequent
> keyspaces are not going to be repaired).
