David Alves commented on CASSANDRA-3047: ---------------------------------------- Hi jonathan I'm not sure I completely understand your suggestion. If I understand correctly the problem is that probe.effectiveOwnership(keyspace) is calculating ring assignment percentages on multiple ring scenarios as if it was a single ring, correct? If these values are incorrectly calculated how would separating the output per dc help? > implementations of IPartitioner.describeOwnership() are not DC aware > -------------------------------------------------------------------- > > Key: CASSANDRA-3047 > URL: https://issues.apache.org/jira/browse/CASSANDRA-3047 > Project: Cassandra > Issue Type: Improvement > Components: Tools > Reporter: Aaron Morton > Assignee: David Alves > Priority: Trivial > Fix For: 1.1.2 > > > 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. -- This message is automatically generated by JIRA.
