-------------------------------------
Summary: 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
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.
