Hi,
I'm operating Spark in standalone cluster configuration (3 slaves) and
have some question.
1. How can I stop a slave on the specific node?
Under `sbin/` directory, there are
`start-{all,master,slave,slaves}` and `stop-{all,master,slaves}`, but
no `stop-slave`. Are there any way to stop the specific (e.g., the
2nd) slave via command line?
2. How can I check cluster status from command line?
Are there any way to confirm that all Master / Workers are up and
working without using Web UI?
Thanks in advance!
