cassandra bolt config uses illegal character in config; makes storm throw exception

[Adrian Mocanu]

Hi all,
I'm trying to learn how to use CassandraCounterBatchingBolt from storm-contrib 
project on github.

When I run my topology in LOCAL CLUSTER MODE, it throws:
InvalidTopologyException(msg:Topology name cannot contain any of the following:
#{"." "/" ":" "\\"})

And I think it's because the Cassandra bolt needs the IP of Cassandra in the 
config. This IP is added the following way:
                clientConfig.put(StormCassandraConstants.CASSANDRA_HOST, 
"10.10.6.80:9160")
which has 2 illegal characters : and .

Has anyone gotten past this exception? If you have please let me know how.

Thanks
-Adrian
