> Admission control queuing should be asynchronous

> Key: IMPALA-5216
> URL: https://issues.apache.org/jira/browse/IMPALA-5216
> Project: IMPALA
> Issue Type: Sub-task
> Components: Backend
> Reporter: Dan Hecht
> Assignee: Bikramjeet Vig
> Priority: Major
> Labels: admission-control, resource-management
> Fix For: Impala 2.13.0, Impala 3.1.0
>
>
> Currently, admission control queuing occurs synchronously w.r.t. the
> {{ExecuteStatement}} client RPC. That is, a query handle is not returned
> until the query is admitted.
> Instead, the queuing should occur on the asynchronous path. That way, the
> client gets a query handle back immediately and can e.g. cancel a query that
> is in the admission control queue.
> We'll also need a way to better expose the progress of a query handle
> (related to IMPALA-124). E.g. that the query is queued for admission and what
> resource(s) it's waiting on.
