Subject [jira] [Commented] (CASSANDRA-12161) dtest failure in counter_tests.TestCounters.upgrade_test
Date Tue, 19 Jul 2016 19:49:20 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-12161?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15384741#comment-15384741
] 

Alex Petrov commented on CASSANDRA-12161:
-----------------------------------------

I can see no correlation between the error log (with timestamp {{02:45:08,632}} and node logs
with timestamps around {{21:05:29,735}}. 
Moreover, it seems that error log is unrelated node dir {{dtest-HnE_0O}} and error log has
{{dtest-0jFLWr}}.
I've tried running the test several dozen times locally and could not reproduce it.
