Subject [jira] Commented: (HIVE-1215) bogus assertion in GroupByOperator.initializeOp
Date Thu, 04 Mar 2010 23:03:27 GMT

    [ https://issues.apache.org/jira/browse/HIVE-1215?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12841591#action_12841591
] 

John Sichi commented on HIVE-1215:
----------------------------------

We have tests for such queries, and we enable assertions in the junit ant task, but we do
not seem to be enabling assertions for the forked JVM's which execute the plan.  We should
find a way to address this in order to get more coverage for assertions (and also to expose
any more bogus ones).
