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 manager.
- 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.
