[jira] [Commented] (DRILL-3031) Project missing a column (empty repeated type)

["Hanifi Gunes (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/DRILL-3031?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14619293#comment-14619293 ] 

Hanifi Gunes commented on DRILL-3031:
-------------------------------------

I am not sure if this is an issue. Drill way of handling list types is lazy meaning that we don't materialize a column until we find out a scalar type within the list. I will mark this a Not-A-Problem please re-open if you think this issue is valid.
