[jira] [Created] (IMPALA-11263) Coordinator hang when cancelling a query

Wenzhe Zhou created IMPALA-11263:
------------------------------------

             Summary: Coordinator hang when cancelling a query
                 Key: IMPALA-11263
                 URL: https://issues.apache.org/jira/browse/IMPALA-11263
             Project: IMPALA
          Issue Type: Bug
          Components: Backend
            Reporter: Wenzhe Zhou


In a rare case, callback function Coordinator::BackendState::ExecCompleteCb() was not called for the corresponding ExecQueryFInstances RPC somehow. This caused coordinator waited indefinitely when cancelling the query.
