[jira] [Commented] (HIVE-4959) Vectorized plan generation should be added as an optimization transform.

    [ https://issues.apache.org/jira/browse/HIVE-4959?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13749867#comment-13749867 ] 

Jitendra Nath Pandey commented on HIVE-4959:
--------------------------------------------

This jira requires all vector expressions to be serializable (HIVE-5126). 
This jira also requires HIVE-5146 for some of the tests to work.

> Currently the query plan is vectorized at the query run time in the map task. It will be much cleaner to add vectorization as an optimization step.
