Description

Subtask under DRILL-2363 to add support for impersonation for Hive storage plugin.

When impersonation is enabled, Drill currently impersonates as process user (user who started the Drillbits) when accessing table metadata/data in Hive. This task is to add support for impersonating the user who issued the query when accessing Hive metadata/data.

Hive authorization investigations, scope, design (wip), configuration and testcases are captured in this documents: https://docs.google.com/document/d/1h7sniix5KPst-qKMh2D8cjjx3uNrw1wx6IkirJ9z7pQ/edit?usp=sharing
