Subject Re: Question about replacing a dead node
Date Tue, 03 Jun 2014 16:18:56 GMT
A dead node is still allocated key ranges, and Cassandra will wait for it
to come back online rather than redistributing its data. It needs to be
decommissioned or replaced by a new node for it to be truly dead as far as
the cluster is concerned.
