[jira] [Commented] (HIVE-21061) CTAS query fails with
IllegalStateException for empty source
[ https://issues.apache.org/jira/browse/HIVE-21061?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16725840#comment-16725840 ]
Riju Trivedi commented on HIVE-21061:
-------------------------------------
IllegalStateException occurs if inputfileFormat is not in list of supportedAcidInputFormats.In case of empty source table, it returns {{ZeroRowsInputFormat}} which is not present in current supported list.
