Arya Goudarzi updated CASSANDRA-4382:
-------------------------------------

    Description: 
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

Noteworthy Configurations:
Ec2MultiRegionSnitch

2. Create the following keyspace:
create keyspace test_app
  with placement_strategy = 'NetworkTopologyStrategy'
  and strategy_options = {us-east-1 : 2}
  and durable_writes = true;

3. nodetool describering test_app

rpc_endpoints:[], endpoint_details:[])
	TokenRange(start_token:85070591730234615865843651859750628464, end_token:127605887595351923798765477788721654896,

rpc_endpoints:[], endpoint_details:[])

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.
