--------------------------------
Labels: impala-iceberg (was: )
> Iceberg metadata table scanner can be scheduled to executors
> ------------------------------------------------------------
>
> Key: IMPALA-12809
> URL: https://issues.apache.org/jira/browse/IMPALA-12809
> Project: IMPALA
> Issue Type: Bug
> Components: Backend
> Affects Versions: Impala 4.4.0
> Reporter: Tamas Mate
> Priority: Major
> Labels: impala-iceberg
>
> On larger clusters the Iceberg metadata scanner can be scheduled to
> executors, for example during a join. The fragment in this case will fail a
> precondition check, because either the frontend_ object will not be present
> or the table. Setting {{exec_at_coord}} to true is not enough and these
> fragments should be scheduled to the {{coord_only_executor_group}}.
>
> Additionally, setting NUM_NODES=1 should be a viable workaround.
