Hyukjin Kwon updated SPARK-61319:
---------------------------------
Fix Version/s: connect-rust-4.3.0
> Connection-layer parity: ChannelBuilder keepalive and userAgent, retried
> release_session, no token in connection-string errors
> ------------------------------------------------------------------------------------------------------------------------------
>
> Key: SPARK-61319
> URL: https://issues.apache.org/jira/browse/SPARK-61319
> Project: Spark
> Issue Type: Bug
> Components: Connect
> Affects Versions: connect-rust-4.3.0
> Reporter: Hyukjin Kwon
> Priority: Major
> Fix For: connect-rust-4.3.0
>
>
> The drop-in ChannelBuilder has no keepalive_* or userAgent properties, so
> DefaultChannelBuilder("sc://host/;grpc_keepalive_time_ms=30000").keepalive_time_ms
> raises AttributeError; PySpark 4.3.0 returns 30000.
> release_session is sent once, so a transient UNAVAILABLE at stop leaves the
> server session until its timeout; PySpark retries it under the retry policy.
> A bad port in a connection string quotes the whole URL, token included
> (sc://localhost:notaport/;token=SECRET); PySpark's message names only the
> port, and a missing host quotes the URL with the token redacted.
