Thomas Tauber-Marshall resolved IMPALA-8712.
--------------------------------------------
Fix Version/s: Impala 3.4.0
Resolution: Fixed
> Convert ExecQueryFInstance() RPC to become asynchronous
> -------------------------------------------------------
>
> Key: IMPALA-8712
> URL: https://issues.apache.org/jira/browse/IMPALA-8712
> Project: IMPALA
> Issue Type: Sub-task
> Components: Distributed Exec
> Affects Versions: Impala 3.3.0
> Reporter: Michael Ho
> Assignee: Thomas Tauber-Marshall
> Priority: Major
> Fix For: Impala 3.4.0
>
>
> Now that IMPALA-7467 is fixed, ExecQueryFInstance() can utilize the async RPC
> capabilities of KRPC instead of relying on the half-baked way of using
> {{ExecEnv::exec_rpc_thread_pool_}} to start query fragment instances. We
> already have a reactor thread pool in KRPC to handle sending client RPCs
> asynchronously. Also various tasks under IMPALA-5486 can also benefit from
> making ExecQueryFInstance() asynchronous so the RPCs can be cancelled.
