SunShun created ZEPPELIN-5644:
---------------------------------
Summary: Optimize the interpreter execution process
Key: ZEPPELIN-5644
URL: https://issues.apache.org/jira/browse/ZEPPELIN-5644
Project: Zeppelin
Issue Type: Improvement
Components: Interpreters
Affects Versions: 0.10.0
Reporter: SunShun
Fix For: 0.11.0
Hi, I found some issues when trying to investigate the spark OOM issue:
# Thread of interpreter executor hasn't been closed when interpreter is closed;
# When restart from notebook page, the Zeppelin Daemon are going to close all
interpreters, while Zeppelin interpreter server only close the opened
interpreters indeed, and it causes in duplicated interpreters kept in server
side;
# After one user starts multi spark sessions, duplicated loaded Classes are
founded for the innerScalaInterpreter inside the spark interpreter, since the
threads are created in different sub threads, and they don't share loaded class.
I will create a PR to solve the above issues.
