Subject [jira] [Commented] (DRILL-1905) UNION ALL of two identical json files fails with exception
Date Wed, 31 Dec 2014 22:06:13 GMT

    [ https://issues.apache.org/jira/browse/DRILL-1905?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14262460#comment-14262460
] 

Jinfeng Ni commented on DRILL-1905:
-----------------------------------

+1.

Looks good to me.

For the change in Calcite, do we need to make sure 'ANY' is NULLable? Seems there is a recent
issue where 'ANY' type is not treated as Nullable.
