Subject [jira] [Commented] (CASSANDRA-7324) Strange warnings during pig-test
Date Fri, 30 May 2014 14:31:04 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-7324?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14013684#comment-14013684
] 

Brandon Williams commented on CASSANDRA-7324:
---------------------------------------------

Thinking about it a bit more, I think the problem is that without this commit it errors so
quickly that the warnings are never produced.
