[jira] [Created] (IMPALA-12208) DCHECK(pending_rpcs_.empty()) fails with concurrent RPCs

             Summary: DCHECK(pending_rpcs_.empty()) fails with concurrent RPCs
                 Key: IMPALA-12208
                 URL: https://issues.apache.org/jira/browse/IMPALA-12208
             Project: IMPALA
          Issue Type: Bug
            Reporter: Kurt Deschler
            Assignee: Kurt Deschler


There is a race condition where concurrent RPCs can register with the ClientRequestState after Finalize has been called. This causes the DCHECK(pending_rpcs_.empty()) since these RPCs are not unregistered in Finalize() as expected.

Issue reproduces with ASAN builds running tests/hs2/test_hs2.py::TestHS2::test_concurrent_unregister in a loop.
