Subject [jira] Commented: (HIVE-1600) need to sort hook input/output lists for test result determinism
Date Fri, 27 Aug 2010 20:05:53 GMT

    [ https://issues.apache.org/jira/browse/HIVE-1600?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12903580#action_12903580

John Sichi commented on HIVE-1600:

Actually it's a pain to change that since a lot of places are already passing around HashSet.
 So I'm going to leave that for a followup since the point of this patch is to fix the sporadic
failures which are hindering testing of other patches.

list for determinism?
