Subject [jira] [Commented] (DRILL-4733) max(dir0) reading more columns than necessary
Date Tue, 21 Jun 2016 00:50:58 GMT

    [ https://issues.apache.org/jira/browse/DRILL-4733?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15340802#comment-15340802

Zelaine Fong commented on DRILL-4733:

The commit id [~rkins] has referenced corresponds to DRILL-3474.  That Jira added new virtual
columns.  As a result of that change, are we now reading more columns than necessary, resulting
in the error?
