--------------------------------------
Summary: Long running logic inside synchronized block in
InterpreterSettingManager
Key: ZEPPELIN-3411
URL: https://issues.apache.org/jira/browse/ZEPPELIN-3411
Project: Zeppelin
Issue Type: Bug
Affects Versions: 0.7.3
Reporter: Jongyoul Lee
Assignee: Jongyoul Lee
Restarting interpreter with an abnormal case, e.g. SparkInterpreter's hang,
it's inside a synchronized block of {{InterpreterSettings}}. It leads other
unintended behaviors like not showing interpreter list when users try to create
a new note and interpreter tab.
