-------------------------------------
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.
