[jira] [Updated] (HIVE-1237) select coalesce(null) from src dies

     [ https://issues.apache.org/jira/browse/HIVE-1237?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ashutosh Chauhan updated HIVE-1237:
-----------------------------------

    Attachment: hive-1237.patch

returnObjectInspector should always be created, otherwise will throw NPE as demonstrated here. Patch which does that. Also, included a test case which fails without patch but passes with the patch.
