      Description

      When adds a new replica and the process fails. Ksck warns about tablet being 'under-replicated' while there are three healthy replicas. We should better improve the message in this case:

      Tablet 848cd6f04bed4f049915ddf04e960240 of table 'ssb_1000_lineorder' is under-replicated: 1 replica(s) not RUNNING

      1 replicas' active configs differ from the master's.
        All the peers reported by the master and tablet servers are:

        B = 70f7ee61ead54b1885d819f354eb3405

        D = cc32936bc8594948a04fd4240da36aed
