Hi Lahiru, What is the version of the Cassandra-gui which you are using ? I am using 0.8.0-beta1 (latest) version and normally you only need to give the host name (ex: localhost) to connect to the Cassandra in that version. I am using default values for other fields ( 7199 for JMX port and 9160 for Thrift port)
We are writing a web service module for MetCat and sample Java Client to retrieve and query data using Cassandra. Currently we are working on it. But we are not dealing with user management with this module for now. Thanks, Hasitha.
