Jay Zhuang updated CASSANDRA-14551: ----------------------------------- Status: Patch Available (was: Open) > ReplicationAwareTokenAllocator should block bootstrap if no replication > number is set > ------------------------------------------------------------------------------------- > > Key: CASSANDRA-14551 > URL: https://issues.apache.org/jira/browse/CASSANDRA-14551 > Project: Cassandra > Issue Type: Bug > Components: Configuration > Reporter: Jay Zhuang > Assignee: Jay Zhuang > Priority: Minor > > We're using > [ReplicationAwareTokenAllocator|https://www.datastax.com/dev/blog/token-allocation-algorithm]. > When bootstrapping a new DC, the tokens are not well distributed. The > problem is because the replication number is not set for the new DC before > the bootstrap. > I would suggest blocking the bootstrap if replication number is not set. It's > unsafe to assume the default replicas is 1.
