JPS in master:
]# jps

in slave I am not able to see jps command output:

Also under the task-manager i don't see any entries. http://10.x.x.x:8081/#/task-manager
回答1:
Did you configure the conf/slaves file? See https://ci.apache.org/projects/flink/flink-docs-stable/ops/deployment/cluster_setup.html#configuring-flink.
The problem with jps doesn't look like a problem with Flink. Is there really a JDK on the slave?
