Arya Goudarzi commented on CASSANDRA-4382:
------------------------------------------
Nevermind. I had to use us-east in strategy options.
> describering returns empty endpoint with NetworkTopologyStrategy

> Key: CASSANDRA-4382
> URL: https://issues.apache.org/jira/browse/CASSANDRA-4382
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Affects Versions: 1.1.1
> Environment: Ubuntu Precise
> 2 x Ec2 m2.xlarge in 2 distinct zone (total 4 nodes)
> Cassandra 1.1.1
> Reporter: Arya Goudarzi
>
> nodetool describering returns empty endpoints with NetworkTopologyStrategy
> and Ec2MultiRegionSnitch.
> Steps to Reproduce:
> 1. Launch a 4 node cluster in 2 distinct Ec2 zones using Cassandra 1.1.1
> binary build. This is how the ring looks like:
> Address DC Rack Status State Load Owns
> Token

> I had asked this in chat yesterday. First in my test environment where I had
> only one local node I was mistakenly using NetworkTopology like above which
> ended up in returning no endpoint, so that was my problem and changing it to
> SimpleStrategy worked. Now I have a 4 node cluster and NetworkTopology seams
> to not work as expected.
> Please investigate. Thank You.
