Subject [jira] [Commented] (HIVE-12954) NPE with str_to_map on null strings
Date Mon, 11 Apr 2016 20:56:25 GMT

    [ https://issues.apache.org/jira/browse/HIVE-12954?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15235962#comment-15235962

Janick Bernet commented on HIVE-12954:
--------------------------------------

This also appears to be in Hive 1.0. The closely related 'split' function does handle NULL
transparently, without an NPE.
