-----------------------------------
Attachment: (was: trunk-1310.txt)
> Disallow KS definition with RF > # of nodes
> -------------------------------------------
>
> Key: CASSANDRA-1310
> URL: https://issues.apache.org/jira/browse/CASSANDRA-1310
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Environment: CentOS 5.1
> Trunc July 22nd
> Reporter: Arya Goudarzi
> Fix For: 0.7.0
>
>
> Cassandra 0.7 allows user to create Keyspaces with Replication Factor >
> number of endpoints causing in java.lang.IllegalStateException: replication
> factor (2) exceeds number of endpoints (1) exception in nodetool and Internal
> Errors on Thrift making the node useless.
> Steps to Reproduce:
> From a clean setup of Cassandra:
> 1. Start a single node out of cluster of 3. This means my configuration has
> the other two nodes in the seeds list, but have not restarted them yet;
> 2. Use Thrift API (I am using PHP) and create a Keyspace with replication
> factor 2;
> 3. The command executes with no exception or error;
> 4. Now try writing to it, you will get TException with Internal Error message;
> 5. Try nodetool ring and you will get Exception:
> Exception in thread "main" java.lang.IllegalStateException: replication
> factor (2) exceeds number of endpoints (1)
