Change subject: IMPALA-11263: Coordinator hang when cancelling a query ...................................................................... IMPALA-11263: Coordinator hang when cancelling a query In a rare case, callback Coordinator::BackendState::ExecCompleteCb() was not called for the corresponding ExecQueryFInstances RPC. This caused coordinator to wait indefinitely when calling Coordinator::BackendState::Cancel() to cancel one fragment instance. This patch added timeout for BackendState::WaitOnExecLocked() so that coordinator will not be blocked indefinitely when cancelling a query. Testing: - Added a test case to simulate the callback missing when a query is failed. Verified that the coordinator would hang without the fixing. - Passed core tests.
