> 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.
