Duplicate nodes showing on the ring when starting 3 nodes on empty cluster
--------------------------------------------------------------------------
Key: CASSANDRA-1341
URL: https://issues.apache.org/jira/browse/CASSANDRA-1341
Project: Cassandra
Issue Type: Bug
Affects Versions: 0.7 beta 1
Environment: CentOS 5.2
Trunk
Reporter: Arya Goudarzi
When bringing a cluster of 3 nodes up, if user does not boot up the nodes
serially and wait for bootstrap to finish on each before restarting the next
one, the cluster may end of having duplication nodes showing on the ring.
Steps to Reproduce:
1. Configure a cluster of 3 from clean slate of trunc;
2. Start the first node;
3. Start the second node;
4. As soon as the second node starts ans says Finished Hinted Handoff to node
1, start node 3;
5. Load the schema from YAML using JMX or use Thrift to define some schema so
that we could use nodetool (CASSANDRA-1286)
I ended up with a strange ring configuration:
[agouda...@cas-test1 ~]$ nodetool --host=10.50.26.132 ring

In my case
10.50.26.132 = node 1
10.50.26.133 = node 2
10.50.26.134 = node 3
As you see node2 is repeated Twice. Node 3 is running however does not show up
in the ring!
Now, if in step 4 if I wait for bootstrap of node 2 to kick in and finish, I
won't have this problem.
