Details
* Currently in the share group heartbeat flow, if we see a TP subscribed for the first time, we move that TP to initializing state in GC and let the GC send a persister request to share group initialize the aforementioned TP. * However, if the coordinator runtime request for share group heartbeat times out (maybe due to restarting/bad broker), the future completes exceptionally resulting in persiter request to not be sent. * Now, we are in a bad state since the TP is in initializing state in GC but not persister initialized. Future heartbeats for the same share partitions will also not help since we do not allow retrying persister request for initializing TPs. * This PR remedies the situation by allowing the same. * A temporary fix to increase offset commit timeouts in system tests was added to fix the issue. In this PR, we revert that change as well. Reviewers: Andrew Schofield <aschofield@confluent.io> |
