## Interpreter Lifecycle Management
Before 0.8.0, Zeppelin don't have lifecycle management on interpreter. User have to shutdown interpreters explicitly via UI. Starting from 0.8.0, Zeppelin provides a new interface
`LifecycleManager` to control the lifecycle of interpreters. For now, there're 2 implementations: `NullLifecycleManager` and `TimeoutLifecycleManager` which is default.
`NullLifecycleManager` will do nothing,
user need to control the lifecycle of interpreter by themselves as before. `TimeoutLifecycleManager` will shutdown interpreters after interpreter idle for a while. By default, the idle threshold is 1 hour.
User can change it via `zeppelin.interpreter.lifecyclemanager.timeout.threshold`. `TimeoutLifecycleManager` is the default lifecycle manager, user can change it via `zeppelin.interpreter.lifecyclemanager.class`.
