Subject [jira] [Commented] (CASSANDRA-11391) "class declared as inner class" error when using UDF
Date Thu, 28 Apr 2016 17:02:13 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-11391?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15262526#comment-15262526
] 

Tyler Hobbs commented on CASSANDRA-11391:
-----------------------------------------

+1 on the code changes.  Can you rebase against the latest trunk and re-run CI?  There are
a lot of dtest failures that are hopefully unrelated.
