Flink Standalone cluster - dumps

We are using standalone cluster and submittig jobs through command line
client.

As far as I understand, the job is executed in task manager. A single task
manager represents a single jvm? So the dump shows threads from all jobs
bound to task manager.
Two questions:

1) Is there a special setting so that each task manager is occupied by a
single job. Can setting slot size to 1 be a workaround?
2) If option above is not possible is there any way to get dump per job?


Regards

1) Setting the slot size to 1 can be used as a work-around. I'm not 
aware of another solution for standalone clusters. In the 
YARN/Kubernetes world we support the notion of a "job cluster", which is 
started and run only for a single job, but this isn't supported in 
standalone mode.
2) None that I'm aware of unfortunately.
