Hey St.Ack
Thanks for clarifications,
For 4. replay of log: (Please correct if i'm wrong)

Hi St.Ack
You asked for it :-)
So in case a RS goes down, the master will split the log and reassign the
regions to other RS, then each RS will replay the log, during this step the
regions are unavailable, and clients will got exceptions.

Not sure I follow Mikael. The master is not in the read/write path so
