            Description

            From running the cluster perf run, I see these two locks as being contended.
            Metric can probably be turned to atomic instructions and we're doing something expensive with the query exec state lock.

            ImpalaServer::query_exec_state_map(52057): 1m3s
Metric(1528664): 3s729ms
