Correct me if i'm wrong.
https://github.com/apache/zeppelin/pull/2668/files#diff-3477d79f3012453f20c3727ec60338e9R230
skips interpreter close when `zeppelin.recovery.enabled` is true. However,
[zeppelin-deamon.sh](https://github.com/apache/zeppelin/blob/master/bin/zeppelin-daemon.sh#L222)
script still kill each individual interpreter process using PID file created
by
[interpreter.sh](https://github.com/apache/zeppelin/blob/master/bin/interpreter.sh#L228)
on `restart` (and `stop`). Isn't it?
