T Jake Luciani commented on CASSANDRA-5780: ------------------------------------------- [~jdsumsion] here's a simple dtest you can use to build a test with https://github.com/riptano/cassandra-dtest/blob/7e7b09d977eb1e113fd4e26fb96bdba3a250a03a/topology_test.py#L87 I'm happy to help on irc if you have any questions (tjake) > nodetool status and ring report incorrect/stale information after decommission > ------------------------------------------------------------------------------ > > Key: CASSANDRA-5780 > URL: https://issues.apache.org/jira/browse/CASSANDRA-5780 > Project: Cassandra > Issue Type: Bug > Components: Tools > Reporter: Peter Haggerty > Assignee: John Sumsion > Priority: Trivial > Labels: lhf, ponies, qa-resolved > Fix For: 2.1.x > > > Cassandra 1.2.6 ring of 12 instances, each with 256 tokens. > Decommission 3 of the 12 nodes, one after another resulting a 9 instance ring. > The 9 instances of cassandra that are in the ring all correctly report > nodetool status information for the ring and have the same data. > After the first node is decommissioned: > "nodetool status" on "decommissioned-1st" reports 11 nodes > After the second node is decommissioned: > "nodetool status" on "decommissioned-1st" reports 11 nodes > "nodetool status" on "decommissioned-2nd" reports 10 nodes > After the second node is decommissioned: > "nodetool status" on "decommissioned-1st" reports 11 nodes > "nodetool status" on "decommissioned-2nd" reports 10 nodes > "nodetool status" on "decommissioned-3rd" reports 9 nodes > The storage load information is similarly stale on the various decommissioned > nodes. The nodetool status and ring commands continue to return information > as if they were part of a cluster and they appear to return the last > information that they saw. > In contrast the nodetool info command fails with an exception, which isn't > ideal but at least indicates that there was a failure rather than returning > stale information. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
