Subject [jira] [Commented] (HIVE-4642) Implement vectorized RLIKE and REGEXP filter expressions
Date Fri, 30 Aug 2013 00:35:52 GMT

    [ https://issues.apache.org/jira/browse/HIVE-4642?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13754249#comment-13754249

Jitendra Nath Pandey commented on HIVE-4642:
--------------------------------------------

Please make these new expressions serializable. HIVE-4959 changes will mandate that all vectorized
expressions are serializable. The VectorExpression class already implements Serializable interface.
