> Raise NO_ACTIVE_SESSION when a stream of a stopped session reattaches, as
> PySpark does
> --------------------------------------------------------------------------------------

> Key: SPARK-61187
> URL: https://issues.apache.org/jira/browse/SPARK-61187
> Project: Spark
> Issue Type: Bug
> Components: Connect
> Affects Versions: connect-rust-4.3.0
> Reporter: Hyukjin Kwon
> Assignee: Hyukjin Kwon
> Priority: Major
> Labels: pull-request-available
> Fix For: connect-rust-4.3.0
>
>
> After stop() closes the client, the RPCs of the session raise
> NO_ACTIVE_SESSION, but a result stream that was still open at stop() kept
> reading: when the server ended the stream (for example after
> senderMaxStreamDuration) and the client had to reattach, ReattachExecute went
> out and the rows kept coming. The reattach and an ExecutePlan sent again
> bypassed the closed-client check. PySpark's iterator reattaches through the
> closed client's stub, which raises NO_ACTIVE_SESSION, so the read fails with
> that error. The fix checks the closed state before each reattach attempt and
> ends the stream with that error.
