Michael Theroux updated CASSANDRA-5264:
---------------------------------------
Affects Version/s: 1.1.9
> Nodetool ring is reporting incorrect Effective ownership after upgrading from
> 1.1.2 -> 1.1.9
> --------------------------------------------------------------------------------------------
>
> Key: CASSANDRA-5264
> URL: https://issues.apache.org/jira/browse/CASSANDRA-5264
> Project: Cassandra
> Issue Type: Bug
> Affects Versions: 1.1.9
> Environment: Amazon AWS Linux, Large instance (8gig of RAM, ephemeral
> storage). 12 Node cluster. Replication Factor 3, all queries performed with
> LOCAL_QUORUM
> Reporter: Michael Theroux
> Priority: Minor
>
> We upgraded from Cassandra 1.1.2 to 1.1.9 yesterday. All indications are the
> upgrade went well. Repair works as expected, and all our data is available.
> Performance is as good, if not better, than it was previously.
> However, nodetool ring is reporting inconsistent and incorrect results. This
> was my ring information before the upgrade:
> Address DC Rack Status State Load
> Effective-Ownership Token
