["Namit Jain (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-1091?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12804393#action_12804393 ] 

Namit Jain commented on HIVE-1091:
----------------------------------

It might be difficult to do so in the current form, since partial results may already be emitted.
You will never know the number of rows remaining, so may never be able to decide whether to switch or not in 
the absence of statistics.

> In my test, even by enabling stream table, it will still take a very long time (actually never get a chance to finish).
