Subject [jira] [Commented] (DRILL-2217) Trying to flatten an empty list should return an empty result
Date Sun, 17 May 2015 00:50:59 GMT

    [ https://issues.apache.org/jira/browse/DRILL-2217?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14546999#comment-14546999
] 

Jason Altekruse commented on DRILL-2217:
----------------------------------------

This is because JIRA is confusing in these cases, the other one is resolved as a duplicate,
it doesn't say anything there about a commit to fix it. This still needs to be fixed as part
of this issue, with some general fixes made recently this may just need to be verified, but
I will hopefully be able to do that soon.
