-----------------------------------
Summary: Re-schedule queries if the executor configuration has
changed while queued in AC
Key: IMPALA-8461
URL: https://issues.apache.org/jira/browse/IMPALA-8461
Project: IMPALA
Issue Type: Improvement
Components: Backend
Affects Versions: Impala 3.3.0
Reporter: Lars Volker
If the executor configuration changes while a query is waiting to be admitted,
we need to reschedule it. The current behavior tries to run it as is which will
then fail. To achieve this, we should call Scheduler::Schedule() from the
AdmissionController and then re-schedule if necessary. We need to think about
ways to detect changes to the executor configuration, but a simple hash might
be good enough.
