Summary: Fix error reporting when AuxErrorInfoPB is present
without an error
Key: IMPALA-9748
URL: https://issues.apache.org/jira/browse/IMPALA-9748
Project: IMPALA
Issue Type: Sub-task
Components: Backend
Reporter: Sahil Takiar
As discussed in
[https://gerrit.cloudera.org/#/c/14824/24/be/src/runtime/query-driver.h@136],
there is a bug in the error reporting path for query retries where it is
possible for the error information set in TryQueryRetry is dropped. The impact
is that the Status details (Status::AddDetail) set in TryQueryRetry won't get
propagated to the client. This should only happen rarely, but it can only
happen the ReportExecStatusRequestPB from a fragment contains a AuxErrorInfoPB
entry, but no Status failure:
