David Capwell commented on CASSANDRA-17199:
-------------------------------------------
In addition, it would be nice to enhance
"org.apache.cassandra.streaming.StreamSession#closeSession" so failure also
documents the "why" within the state rather than dumping only to the logs, this
would make the information accessible via the vtable and the summary (rather
than saying peer 42 failed, we can say why it failed)
> Provide summary of failed SessionInfo's in StreamResultFuture

> Key: CASSANDRA-17199
> URL: https://issues.apache.org/jira/browse/CASSANDRA-17199
> Project: Cassandra
> Issue Type: Improvement
> Components: Observability/Logging
> Reporter: Brendan Cicchi
> Priority: Normal
> Labels: AdventCalendar2021, lhf
> Fix For: 4.0.x
>
>
> Currently, we warn about the presence of one or more failed sessions existing
> in the final state and then an operator/user traces back through the logs to
> find any failed streams for troubleshooting.
> {code:java}
> private synchronized void maybeComplete()
> {
> if (finishedAllSessions())
> {
> StreamState finalState = getCurrentState();
> if (finalState.hasFailedSession())
> {
> logger.warn("[Stream #{}] Stream failed", planId);
> tryFailure(new StreamException(finalState, "Stream failed"));
> }
> else
> {
> logger.info("[Stream #{}] All sessions completed", planId);
> trySuccess(finalState);
> }
> }
> } {code}
> It would be helpful to log out a summary of the SessionInfo for each failed
> session since that should be accessible via the StreamState.
>
> This can be especially helpful for longer streaming operations like bootstrap
> where the failure could have been a long time back and all recent streams
> leading up to the warning actually are successful.
