When i try to run the SchemaManipulation example provided by the hector wiki, when the server is started the first time the server is run everything works perfectly, however after a second run errors occur (full stack trace below)
Im trying to connect to cassandra 1.0.7 using hector 1.0.2 and Glassfish 3.1. I'm using Netbeans 7.1.
Custom JARs that have been imported
First run (successful):
SEVERE: log4j:WARN No appenders could be found for logger (me.prettyprint.cassandra.connection.CassandraHostRetryService).
SEVERE: log4j:WARN Please initialize the log4j system properly.

Due to using the SchemaManipulation example and lack of Cassandra experience, ive not realised that the example shuts down the cluster once it has finished executing.
This closes open pools and kills the conndection, for anyone else that comes accross this, just dont shut down the cluster at the end of the class
//remove this as it kills the cluster.
cluster.getConnectionManager().shutdown();
