Jay Zhuang created CASSANDRA-14551: -------------------------------------- Summary: 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
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} -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
