Assignee: Sahil Takiar
> Impala hits DCHECK in ClientRequestState due to invalid state transition
> ------------------------------------------------------------------------
>
> Key: IMPALA-9267
> URL: https://issues.apache.org/jira/browse/IMPALA-9267
> Project: IMPALA
> Issue Type: Bug
> Components: Backend
> Affects Versions: Impala 3.4.0
> Reporter: Joe McDonnell
> Assignee: Sahil Takiar
> Priority: Blocker
> Labels: broken-build
> Attachments: backtrace.txt
>
>
> Some test runs see the coordinator Impalad hit this DCHECK:
> {code:java}
> case ExecState::FINISHED:
> // A query can transition from PENDING to FINISHED if it is cancelled by the
> // client.
> DCHECK(old_state == ExecState::PENDING || old_state == ExecState::RUNNING)
> << Substitute(
> error_msg, ExecStateToString(old_state),
> ExecStateToString(new_state));
> UpdateExecState(new_state);
> break;{code}
> The error message is:
> {noformat}
> F1222 23:01:14.020613 10494 client-request-state.cc:951] Check failed:
> old_state == ExecState::PENDING || old_state == ExecState::RUNNING Illegal
> state transition: ERROR -> FINISHED{noformat}
> This happened on one exhaustive run on Centos6 and an s3 run. There doesn't
> seem to be a pattern, so I'm assuming this is a generic issue.
