Key: CASSANDRA-3047
URL: https://issues.apache.org/jira/browse/CASSANDRA-3047
Project: Cassandra
Issue Type: Improvement
Components: Core
Affects Versions: 0.8.4
Reporter: Aaron Morton
Priority: Trivial
see http://www.mail-archive.com/user@cassandra.apache.org/msg16375.html
When a cluster the multiple rings approach to tokens the output from nodetool
ring is incorrect.
When it uses the interleaved token approach (e.g. dc1, dc2, dc1, dc2) it will
be correct.
It's a bit hacky but could we special case (RP) tokens that are off by 1 and
calculate the ownership per dc ? I guess another approach would be to add some
parameters so the partitioner can be told about the token assignment strategy.
