You seem to have a disregard for the user/operator's poor experience. If no effort to redress
this, I'm -1.

[~saint.ack@gmail.com], if server (Master/RS) is not configured correctly, there is no way
to detect this on a client side (where we execute backup/restore commands)

What happens when distributed log roll procedure is not installed and we run backup command?

# Client issues backup
# Client executes HBaseAdmin.execProcedure("") for logroll-proc
# Master returns ServiceException ("The procedure is not registered)
# client RPC layer catches exception and repeats call after timeout until max attempts is
reached

PRC timeout = 60 sec, max attempts = 31.

Client will stuck for almost half an hour. That is not backup issue, but general HBase RPC
layer flaw.
