Date Tue, 09 Jul 2013 01:06:48 GMT

    [ https://issues.apache.org/jira/browse/HIVE-4801?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13702733#comment-13702733

Edward Capriolo commented on HIVE-4801:
---------------------------------------

I think we should:
1) apply your patch
2) warn when hive.mapred.map.tasks.speculative.execution is set
3) warn when hive.mapred.reduce.tasks.speculative.execution is set
