Subject [jira] [Commented] (CASSANDRA-12098) dtest failure in secondary_indexes_test.TestSecondaryIndexes.test_only_coordinator_chooses_index_for_query
Date Fri, 01 Jul 2016 18:13:11 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-12098?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15359400#comment-15359400
] 

Sam Tunnicliffe commented on CASSANDRA-12098:
---------------------------------------------

I'm going to say that this is unrelated to the actual area under test (i.e. the index functionality)
because the error in the log is a) symptomatic of a schema mismatch on the base table b) occurring
during the initial data setup, not the main test code. 

This specific failure is the only instance in the available history of both the offheap (where
this isolated failure occurred) and the main dtest jobs. Given that, I'm hesitant to just
mark it as flakey. I also failed to repro in 100 iterations on either job ([onheap|https://cassci.datastax.com/view/Parameterized/job/parameterized_dtest_multiplexer/156/],
[offheap|https://cassci.datastax.com/view/Parameterized/job/parameterized_dtest_multiplexer/158/]).

There have been are some other failures on the offheap jobs recently, so I'll spend a bit
of time digging there and also go over the attached logs again.
