[jira] Commented: (HIVE-498) UDFRegExp NullPointerException on empty replacement string

    [ https://issues.apache.org/jira/browse/HIVE-498?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12711298#action_12711298 ] 

Prasad Chakka commented on HIVE-498:
------------------------------------

isn't the check 'p == null' redundant since p is set to null and not modified before this check?

> UDFRegExp NullPointerException on empty replacement string
