## Interpreter Process Recovery
Before 0.8.0, shutting down Zeppelin also mean to shutdown all the running interpreter processes. Usually admin will shutdown zeppelin server for maintenance or upgrade, but don't want to shut down the running interpreter process.
Before 0.8.0, shutting down Zeppelin also mean to shutdown all the running interpreter processes. Usually admin will shutdown Zeppelin server for maintenance or upgrade, but don't want to shut down the running interpreter processes.
In such cases, interpreter process recovery is necessary. Starting from 0.8.0, user can enable interpreter process recovering via setting `zeppelin.recovery.storage.class` as
`org.apache.zeppelin.interpreter.recovery.FileSystemRecoveryStorage` or other implementations if available in future, by default it is `org.apache.zeppelin.interpreter.recovery.NullRecoveryStorage`
which means recovery is not enabled. Enable recover means shutting down zeppelin would not terminating interpreter process,
and when zeppelin is restarted, it would try to reconnect to the existing running interpreter process. If you want to kill all the interpreter process after terminating zeppelin even when recovery is enabled, you can run `bin/stop-interpreter.sh`
