Prasanth Jayachandran updated HIVE-17508:
-----------------------------------------
    Attachment: HIVE-17508.WIP.patch

Attaching a WIP patch. This still has to be hooked to metastore objects. For query elapsed time, hive.query.timeout.seconds can be used which will fail the query exceeding timeout.

> Workload management can defined Rules that are bound to a resource plan. Each rule can have a trigger expression and an action associated with it. Trigger expressions are evaluated at runtime after configurable check interval, based on which actions like killing a query, moving a query to different pool etc. will get invoked. Simple rule could be something like
> {code}
> CREATE RULE slow_query IN resource_plan_name
> WHEN execution_time_ms > 10000
> MOVE TO slow_queue
> {code}
