Errors when trying to get a connection to cassandra

I'm trying to create a Java program that uses a Cassandra database. I'm 'trying' to use Hector client but when I run I'm getting some errors. I have searched on the internet but could find a fix that worked for me (it's probably something obvious).

Libs I included in my build path:

hector
libthrift-0.9.1
slf4j-simple-1.75

Errors im getting:

[main] INFO me.prettyprint.cassandra.connection.CassandraHostRetryService - Downed Host Retry service started with queue size -1 and retry delay 10s
[main] INFO me.prettyprint.cassandra.service.JmxMonitor - Registering JMX me.prettyprint.cassandra.service_Test Cluster:ServiceType=hector,MonitorType=hector

That class seems to be in the cassandra-thrift library which you can find here.
