[jira] [Commented] (HIVE-2402) Function like with empty string is
throwing null pointer exception
[ https://issues.apache.org/jira/browse/HIVE-2402?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13094196#comment-13094196 ]
John Sichi commented on HIVE-2402:
----------------------------------
I'm curious: why is it not possible to actually support an empty string as the like pattern? It's not particularly useful, but should be no different from any other wildcardless pattern.
