             Summary: Fault injection at DescriptorTbl::Create() can lead to query hang
                 Key: IMPALA-5892
                 URL: https://issues.apache.org/jira/browse/IMPALA-5892
             Project: IMPALA
          Issue Type: Bug
          Components: Backend
    Affects Versions: Impala 2.9.0
            Reporter: Joe McDonnell
            Assignee: Joe McDonnell


When doing fault injection testing, I found that QueryState::ReportExecStatusAux() does not include enough information for the coordinator to detect an error when 'fis' is null. Specifically, TReportExecStatusParam does not include status unless a TFragmentInstanceExecStatus is inserted into instance_exec_status, and that structure requires a fragment instance id. For a general error (such as one reported via ReportExecStatusAux() in QueryState::StartFInstances() when DescriptorTbl::Create() fails), this lack of status information means that the coordinator will never detect that the query failed for certain error condtitions.

TReportExecStatusParam needs to include a general status field for reporting this information.
