Hi Chesnay,
Yes, it is. Later I notice before the later started cluster I have use
./bin/start-cluster.sh to start a local cluster, and after I
./bin/stop-cluster.sh to stop the cluster, the problem is gone.
But how the later started cluster know there is a job in the former
started cluster?
Best
Henry
