> Key: SPARK-49458
> URL: https://issues.apache.org/jira/browse/SPARK-49458
> Project: Spark
> Issue Type: Bug
> Components: Connect
> Affects Versions: 4.0.0
> Reporter: Changgyoo Park
> Priority: Major
>
> Related to SPARK-47380.
> Driver restart -> OPERATION_NOT_FOUND instead of SESSION_NOT_FOUND because
> the first request of a certain message type is always verified as legit in
> the current implementation.
> E.g.,
> Start execution (client_observed_server_side_session_id is set) -> driver
> restart -> reattach (client_observed_server_side_session_id is not set) ->
> OPERATION_NOT_FOUND instead of SESSION_NOT_FOUND.
