----------------------------------

hi [~trohrmann], thanks for your response vert much.
but it is not product environment used in standalone application model/per job 
model. because it needs user to start taskmanager while spark worker process 
can start executor (just like flink taskmanager)in standalone model, especially 
there are many jobs.

> flink standalone Isolation is poor, why not do as spark does

> flink standalone Isolation is poor, why not do as spark does.
> spark abstract cluster manager, executor just like flink taskmanager.
> spark worker(standalone) is process, and executor is as child process of 
> worker.
