tholzer commented on CASSANDRA-1111:
------------------------------------
I can reproduce this with the following:
Linux & Python 2.6.4
{noformat}
from thrift.transport.TSocket import TSocket
from thrift.protocol.TBinaryProtocol import TBinaryProtocol
from cassandra.Cassandra import Client
if __name__ == "__main__":
tsocket = TSocket('localhost', 9160)
tsocket.open()
tprotocol = TBinaryProtocol(tsocket)
client = Client(tprotocol)
keyspaces = client.describe_keyspaces()
for keyspace in keyspaces:
print "%s" % client.describe_ring(keyspace)
{noformat}
Output:
{noformat}
[TokenRange(end_token='107294900513650794844962875501795914878',

> Key: CASSANDRA-1111
> URL: https://issues.apache.org/jira/browse/CASSANDRA-1111
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Affects Versions: 0.6
> Environment: Mac OS X Snow Leopard
> Reporter: Dominic Williams
> Assignee: Gary Dusbabek
> Fix For: 0.6.2
>
> Original Estimate: 0.75h
> Remaining Estimate: 0.75h
>
> You use Thrift to call describe_ring() on a cluster with only a single node.
> The Thrift connection is broken, and the system.log shows the exception that
> has been thrown:
> ERROR [pool-1-thread-15] 2010-05-20 13:15:24,753 TThreadPoolServer.java (line
> 259) Error occurred during processing of message.
