Hi Flink-Users, I am not sure if this does something to my cluster or not. But since updating to Flink 1.15 (atm rc4) I find the following logs:
INFO: Registering job manager ab7db9ff0ebd26b3b89c3e2e56684...@akka.tcp:// fl...@flink-jobmanager-xxx.com:40015/user/rpc/jobmanager_2 for job 5566648d9b1aac6c1a1b78187fd56975. as many times as number of parallelisms (here 10 times). These logs are triggered every 5 minutes. Then they are followed by: INFO: Registration of job manager ab7db9ff0ebd26b3b89c3e2e56684762 @akka.tcp://fl...@flink-jobmanager-xxx.com:40015/user/rpc/jobmanager_2 failed. also 10 log entries. I followed the lifetime of the job (5566648d9b1aac6c1a1b78187fd56975), it was a long-running sql streaming job, started on Apr 13th on a standalone cluster. After some recovery attempts it finally failed (using the failover strategy) on the 20th Apr (yesterday) for good. Then those logs started to appear. Now there was no other job running on my cluster anymore but the logs appeared every 5 minutes until I restarted this jobmanager service. This job was just an example, it happens to other jobs too. It's just INFO logs but it does not look healthy either. Thanks & Best Peter
