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.
Best,
Gary
