Subject [jira] [Updated] (HIVE-4315) enable doAs in unsecure mode for hive server2, when MR job runs locally
Date Mon, 15 Apr 2013 21:06:16 GMT

     [ https://issues.apache.org/jira/browse/HIVE-4315?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Thejas M Nair updated HIVE-4315:
--------------------------------

    Description: 
When MR job is run locally by hive (instead of hadoop cluster), the MR job ends up running
as hiveserver user instead of the user submitting the query, even if doAs configuration is
enabled.

This is seen in case of map-side join (see [map join optimization|https://cwiki.apache.org/confluence/display/Hive/MapJoinOptimization]
, where there is a MapredLocalTask that is spawned to process the file before adding it to
distributed cache.). When hive.server2.enable.doAs is enabled, MapredLocalTask has to run
as the user submitting the query.
