[jira] [Created] (IMPALA-14359) Investigate race situation in ExecuteStatement vs ExecDdlRequestImpl

Riza Suminto created IMPALA-14359:
-------------------------------------

             Summary: Investigate race situation in ExecuteStatement vs ExecDdlRequestImpl
                 Key: IMPALA-14359
                 URL: https://issues.apache.org/jira/browse/IMPALA-14359
             Project: IMPALA
          Issue Type: Task
            Reporter: Riza Suminto


IMPALA-14348 reveals a data race between ImpalaServer::ExecuteStatement (ExecuteStatementCommon) vs async ClientRequestState::ExecDdlRequestImpl on ClientRequestState::result_metadata_. While it can be solved by acquiring CRS lock in impala-hs2-server.cc, further investigation is needed since having ClientRequestState::ExecDdlRequestImpl finished ahead of ImpalaServer::ExecuteStatement might be abnormal and incorrectly handled.

This Jira is filed to follow up with that investigation.
