Wenzhe Zhou has uploaded a new patch set (#2). ( http://gerrit.cloudera.org:8080/16437 )
Change subject: IMPALA-10154: Fix data race on coord_backend_id in TSAN build ...................................................................... IMPALA-10154: Fix data race on coord_backend_id in TSAN build This issue was introduced by the patch for IMPALA-5746. QueryState::exec_rpc_params_.coord_backend_id is set in function QuestState::Init(), but it could be accessed by QueryExecMgr object in QueryExecMgr::CancelQueriesForFailedCoordinators() before or during QueryState::Init() is called, hence cause data race. To fix it, move coord_backend_id from class ExecQueryFInstancesRequestPB to class TQueryCtx. QueryState::query_ctx_ is a constant variable and is set in QueryState c'tor so that QueryState::query_ctx_.coord_backend_id is valid and will not be changed once the QuestState object is created. Testing: - Passed tests/custom_cluster/test_process_failures.py. - Passed the core tests for normal build. - Passed the core tests against a TSAN build.
