1 replicas' active configs differ from the master's.
All the peers reported by the master and tablet servers are:
A = 3c305734ab9d4e0ebfbd0def74841a5d
B = 70f7ee61ead54b1885d819f354eb3405
C = 72fcec63e96f4248ae39d114eb3cd7c9
D = cc32936bc8594948a04fd4240da36aed
The consensus matrix is:
Config source | Voters | Current term | Config index | Committed?
