Subject [jira] [Commented] (DRILL-5226) External Sort encountered an error while spilling to disk
Date Thu, 02 Mar 2017 19:14:45 GMT

    [ https://issues.apache.org/jira/browse/DRILL-5226?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15892815#comment-15892815
] 

Rahul Challapalli commented on DRILL-5226:
------------------------------------------

[~zelaine] My bad. I kind of mixed it up. The first 2 scenarios's only happen on the old sort.
The 3rd(last) scenario happens on both the old sort and the managed sort as well.

I can raise a different bug for the managed sort issue
