Jeremiah Jordan updated CASSANDRA-11848:
----------------------------------------
Description:
When you do a replace address and the new node has the same IP as the node it
is replacing, then the following check can let the replace be successful even
if we think all the other nodes are down:
https://github.com/apache/cassandra/blob/cassandra-2.1/src/java/org/apache/cassandra/dht/RangeStreamer.java#L271
As the FailureDetectorSourceFilter will exclude the other nodes, so an empty
stream plan gets executed.
