We are seeing this problem as well, regularly actually. Especially in
situations when we have many concurrent interpreters running.

Have similar experience, although hard to say what's the reason as all
process supposed to killed, as Moon pointed out.
Also noticed that with `mvn tests`, after almost every run, there are 1-2
zombie RemoteInterpreter processes hanging around.

I believe I see this before too.

I have also seen similar issues even using zeppelin-ddeamon but didn't have
much time to investigate the issue when it was happening to me.

Unfortunatally, this does not happen all the time.
I have seen zombie spark interpreter processes many times.
As a double conirmation - I see spark yarn application was still running.

How to make Interpreter processes terminate if Zeppelin server exits?
When we restart Zeppelin server (main process), in many cases, Interpreter
process keeps running, essential becoming a zombie processes.
In case of Spark interpreter, it also holds SparkContext - consuming
server-side
resources
