Subject [jira] [Commented] (CASSANDRA-10073) Counter mutation serialization bug
Date Sun, 16 Aug 2015 18:37:46 GMT


Sylvain Lebresne commented on CASSANDRA-10073:

CI results: [utests|] and [dtests|].

Compared to the last results on the cassandra-3.0 branch:
* for the unit tests, there is a failure of {{org.apache.cassandra.cql3.MaterializedViewLongTest.testConflictResolution}}
but I can't really imagine how the patch here could in any way influence that test so I strongly
suspect a flaky test.
* for the dtests, it fixes the test of the description as expected (in fact, the run has only
27 failures compared to 33 on the last cassandra-3.0 run, but the rest is probably flaky tests
for which the run got lucky).
