Jinglun updated RATIS-1911:
---------------------------
Description:
The 《CONSENSUS: BRIDGING THEORY AND PRACTICE》 has explain the JOINT consensus,
which is implemented by ratis. But it didn't say how to configure the initial
conf for new peers. I didn't find demonstration in ratis either.
Initial conf for new peers is easy to make mistakes and cause split brain or
cluster unavailable. I think we can add an example to illustrate how to
initiate new peers when performing membership change.

Initial conf for new peers is easy to make mistakes and cause split brain or
cluster unavailable as I will explain. I think we can add an example to
illustrate how to initiate new peers when performing membership change.
The dilemma when performing membership changes is described in RATIS-1912 with
more details.
