Dikang Gu created CASSANDRA-12983:
-------------------------------------
Summary: NoReplicationTokenAllocator should work with zero
replication factor as well.
Key: CASSANDRA-12983
URL: https://issues.apache.org/jira/browse/CASSANDRA-12983
Project: Cassandra
Issue Type: Improvement
Reporter: Dikang Gu
Assignee: Dikang Gu
Fix For: 3.12
In our production env, when we expand an existing cluster to a new DC, we are
doing following steps:
1. set replication factor to be 0 for the new DC.
2. bootstrap all nodes in the new DC.
3. set the replication factor to be 1 and start the rebuild.
I find the NoReplicationTokenAllocator does not work with replication factor 0,
and this patch will fix it.
