----------------------------------------

             Summary: AssertionError in nodetool cfhistograms
                 Key: CASSANDRA-10859
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-10859
             Project: Cassandra
          Issue Type: Bug
            Reporter: Jim Witschey
             Fix For: 3.0.x, 3.x


{{nodetool cfhistograms}} raises an {{AssertionError}} on the CassCI {{trunk}} jobs:

http://cassci.datastax.com/job/trunk_dtest/lastCompletedBuild/testReport/jmx_test/TestJMX/cfhistograms_test/history/

This regression started in this build on CassCI and has failed consistently since then:

http://cassci.datastax.com/job/trunk_dtest/806/testReport/junit/jmx_test/TestJMX/cfhistograms_test/

I can't find any recent dtest changes to this method, so I believe it's a Cassandra bug. Here's the changeset for the first failing build:

http://cassci.datastax.com/job/trunk_dtest/806/changes

Maybe something in the changes to the scripts here introduced the bug:

https://github.com/apache/cassandra/commit/b5240204d7aa2a32c6649d19da2b961c856cde28

[~jjordan] could you have a look at this please?

This appears to only affect {{trunk}} at present.
