> Project: Hive
> Issue Type: Bug

>
> 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. But by
> default, in case of unsecure (ie without kerberos security) mode hadoop
> considers user the process runs as the user.
