[jira] [Commented] (DRILL-1293) Select star column from a view that
contains star column causes AssertionError
[ https://issues.apache.org/jira/browse/DRILL-1293?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14095177#comment-14095177 ]
Aman Sinha commented on DRILL-1293:
-----------------------------------
Uploaded patch with a fix for the assertion error. There is a remaining issue with duplicate columns in the output when querying the view but that is related to planning, not execution and will be addressed separately.
