Hi Chen, I agree this is not very user friendly & there should be no need to restart LivyInterpreter. One short term fix may be to increase the livy session timeout by changing livy.server.session.timeout (takes time in millisecond)
Filed https://issues.apache.org/jira/browse/ZEPPELIN-1293 to track it.
