[jira] [Commented] (HIVE-9430) NullPointerException on ALTER TABLE ADD PARTITION if no value given

    [ https://issues.apache.org/jira/browse/HIVE-9430?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14301391#comment-14301391 ] 

Sergio Peña commented on HIVE-9430:
-----------------------------------

hi [~szehon]

This patch only handles the NPE. 
However, a better message is thrown later in the code when a null value is detected. This is already implemented and works well.
