Hi Gary, Here are the full job manager and task manager logs. In the job manager logs, I see it says “starting StandaloneSessionClusterEntrypoint”, whereas in Flink 1.4.2, it used to say “starting JobManager”. Is this correct?
Job manager logs: https://paste.ubuntu.com/p/DCVzsQdpHq/ (https://paste(.)ubuntu(.)com/p/DCVzsQdpHq /<https://paste(.)ubuntu(.)com/p/DCVzsQdpHq%20/>) Task Manager logs: https://paste.ubuntu.com/p/wbvYFZxdT8/ (https://paste(.)ubuntu(.)com/p/wbvYFZxdT8/) Thanks, Harshith From: Gary Yao <g...@ververica.com> Date: Thursday, 14 March 2019 at 10:11 PM To: Harshith Kumar Bolar <hk...@arity.com> Cc: user <user@flink.apache.org> Subject: [External] Re: Re: Flink 1.7.2: Task Manager not able to connect to Job Manager Hi Harshith, The truncated log is not enough. Can you share the complete logs? If that's not possible, I'd like to see the beginning of the log files where the cluster configuration is logged. The TaskManager tries to connect to the leader that is advertised in ZooKeeper. In your case the "cluster" hostname is advertised which hints a problem in your Flink configuration.
