[jira] [Created] (IMPALA-8712) Convert ExecQueryFInstance() RPC to become asynchronous

Michael Ho created IMPALA-8712:
----------------------------------

             Summary: Convert ExecQueryFInstance() RPC to become asynchronous
                 Key: IMPALA-8712
                 URL: https://issues.apache.org/jira/browse/IMPALA-8712
             Project: IMPALA
          Issue Type: Improvement
          Components: Distributed Exec
    Affects Versions: Impala 3.3.0
            Reporter: Michael Ho
            Assignee: Thomas Tauber-Marshall


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.
