Description

Hello,

We noticed that, sometimes, interpreter related processes become zombie.

After restarting interpreter, some zombie processes stil exist.

in some cases, these processes persist after restarting Zeppelin

I did the test with Spark and livy interpreters: I get yhe same behavior.

I know that this kind of issue was mentioned in Jira ZEPPELIN-1832 which is marked as resolved. But it seems that there is a regression.

 

Did any one encounter this problem?

 

Best regards

Sabri
