Github user cloverhearts commented on the issue: https://github.com/apache/zeppelin/pull/1838 But actually this is a temporary resolved. As a result, Zombie Process issues have been mitigated. Zomebie Process is very important and risky issue. So, I felt the need to take minimal steps. This fix minimizes the potential for Zombie. I forced the reference count to zero at shutdown to terminate the process. The exact problem with the Zombie Process is: 1. Interpreter reference count management failure 2. Close failed while working on RemoteInterpreter 3. Close the RemoteInterpreter Unknown stop. 4. Termination timing issues not yet discovered .. Therefore, I feel it is necessary to take temporary measures through this PR, to register detailed issues and gradually resolve them. What do you think?
