Subject Re: Question in the tutorial
Date Fri, 12 Jul 2019 03:12:03 GMT
Hi Karthik,

I think more information is needed for diagnosing the problem, and I would
suggest you to do the followings:
- Check whether the task managers are configured in the file 'conf/slaves'.
  - If configured, you should see some hosts in the file, each for one task
- Check whether the task managers are running, by execute the command 'ps
-ef | grep TaskManagerRunner'.
  - If there are task managers running, you should be able to see the
corresponding processes.
- Checks jobmanager / taskmanager logs to find out why the task managers
are not started, or started, but not find by the cluster.
  - You can find the logs in 'log/flink-*-standalonesession-*.log'.
  - If you cannot find the problem from the logs, you can also post them in
this ML for help.

Thank you~
