Review comment:
Javadocs are useful to keep the history behind these things. Keep in mind
that the method is only public (java delimiter access); this means accessible
to programmers to re-use its code. It is not something that end-users will have
access to.

> Reporter: Wei Zhou

> Priority: Major

> for now, restartnetwork with cleanup will stop both RVRs at first, then start
> two new RVRs.
> to reduce the downtime of network, we'd better restart the RVRs one by one.
