> 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. Which also causes the following
> invalid stats:
> {noformat}
> WARN [main] 2018-06-29 17:30:55,696 TokenAllocation.java:69 - Replicated
> node load in datacenter before allocation max NaN min NaN stddev NaN
> WARN [main] 2018-06-29 17:30:55,696 TokenAllocation.java:70 - Replicated
> node load in datacenter after allocation max NaN min NaN stddev NaN
> {noformat}
