> 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
> Assignee: Lars Volker
> Priority: Major
>
> 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.
