[jira] [Commented] (HIVE-4685) query using LIKE does not vectorize,
then crashes
[ https://issues.apache.org/jira/browse/HIVE-4685?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13678206#comment-13678206 ]
Jitendra Nath Pandey commented on HIVE-4685:
--------------------------------------------
I suspect this is same as HIVE-4599. I have a patch on HIVE-4599, which should hopefully fix the issue of query crashing.
