Description

When we use yarn --daemon status router/nodemanager, I found that no information can be displayed. I checked the script and modified the script of hadoop-functions.sh#status to increase the output information.

yarn --daemon status router

• If the service is started
  router is running as process 47626.

• If the service is stop
  router is stopped.
