We are having the same problem as described in https://issues.apache.org/jira/browse/ZEPPELIN-2197
We have one interpreter each user and we have a lot of users. Basically resources got sucked up by all those idled interpreters. There is one comment --- Kill it after idle for a while. How do you tell whether an interpreter is idled? So does anyone has any workaround in terms of how to manage the lifecycle of interpreters?
