Subject [jira] Commented: (HIVE-1179) Add UDF array_contains
Date Tue, 25 May 2010 21:51:34 GMT

    [ https://issues.apache.org/jira/browse/HIVE-1179?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12871380#action_12871380

Paul Yang commented on HIVE-1179:
---------------------------------

Yeah, I see your concern, but we're using mutable objects for performance reasons in this
case and I believe there is an assumption that you shouldn't keep references to objects passed
through the operator DAG (in general).
