Again it could not find the state store file: "Caused by:
java.io.FileNotFoundException:
/flink/ha/submittedJobGraph0c6bcff01199 " Check why its unable to
find.
Better thing is: Clean up zookeeper state and check your configurations,
correct them and restart cluster.
Otherwise it always picks up corrupted state from zookeeper and it will
never restart

Is it filesystem or hadoop? If its NAS then why the exception "Caused by:
org.apache.hadoop.hdfs.BlockMissingException: "It seems you configured
hadoop state store and giving NAS mount.

Following are the mandatory condition to run in HA:
a) You should have persistent common external store for jobmanager and task
managers to while writing the state
b) You should have persistent external store for zookeeper to store the
Jobgraph.
Zookeeper is referring path:
/flink/checkpoints/submittedJobGraph480ddf9572ed to get the job graph but
jobmanager unable to find it.
It seems /flink/checkpoints is not the external persistent store
