Review comment:
       Actually, when IoTDB close and restart using API, we don't get a new Instance of MManager. If we didn't set `isRecovering = true` here, the value of `isRecovering` would be null.

Review comment:
       Actually, when close and restart the IoTDB using API, we don't get a new Instance of MManager. If I didn't set `isRecovering = true` here, the value of `isRecovering` would be null.
