[jira] [Commented] (HIVE-12884) NullPointerException in
HiveParser.regularBody()
[ https://issues.apache.org/jira/browse/HIVE-12884?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15105015#comment-15105015 ]
Bohumir Zamecnik commented on HIVE-12884:
-----------------------------------------
So the query was malformed. There's missing comma between day_timestamp and count(*) as guid_count.
Anyway the parser should report a syntax error, not fail on a NPE.
