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.
In case of map-side join (see [map join
optimization|https://cwiki.apache.org/confluence/display/Hive/MapJoinOptimization])
, MapredLocalTask is spawned in child process to process the map-side file
before adding it to distributed cache. When hive.server2.enable.doAs is
enabled, MapredLocalTask should run as the user submitting the query.
was:
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 MapredLocalTask that is spawned to process the file before adding it
to distributed cache.). When hive.server2.enable.doAs is enabled,
MapredLocalTask should run as the user submitting the query.
> enable doAs in unsecure mode for hive server2, when MR job runs locally
