Subject [jira] [Commented] (DRILL-1638) Text plan should contain information about text partitions
Date Tue, 11 Nov 2014 02:03:34 GMT

    [ https://issues.apache.org/jira/browse/DRILL-1638?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14205805#comment-14205805

Hanifi Gunes commented on DRILL-1638:
-------------------------------------

I doubt if scan has knowledge of partitions or input splits. Current fix just outputs the
list of files.
