Subject Re: Is it *safe* to issue multiple replace-node at the same time?
Date Tue, 22 Nov 2016 13:12:37 GMT
It's safe but since the replacement node will stream data from a single
replica per local range, it will potentially propagate any inconsistencies
from the replica it streams from, so it's recommended to run repair after a
replace to reduce entropy specially when replacing a node with the same IP
due to CASSANDRA-12344.
