I have NOI 1.6.3 in a production environment, running 7 pods of kafka. 3 of these pods are not working with a mount issue problem I am trying to solve.
Currently, I am getting the following errors in the Kafka pods that are running:
[2021-11-23 20:37:48,838] ERROR [noi-hybrid-shared1-kafka 0] [Broker id=0] Received LeaderAndIsrRequest with correlation id 1 from controller 1 epoch 9 for partition noi-requests-5 (last update controller epoch 9) but cannot become follower since the new leader -1 is unavailable. (state.change.logger)[2021-11-23 20:38:21,076] INFO [noi-hybrid-shared1-kafka 0] [ReplicaFetcher replicaId=0, leaderId=2, fetcherId=0] Retrying leaderEpoch request for partition asm.netcool.events.json-19 as the leader reported an error: UNKNOWN_TOPIC_OR_PARTITION (kafka.server.ReplicaFetcherThread)To me, it seems it lost some references (probably due to the mount problem in the other pods) and now it is not working.
I was wondering if I could restart it fresh, i.e., clean up any current data/messages/references in Kafka and let it start from scratch. Is it possible?
Any help is really appreciated. Thanks in advance, Fernando.
