Hi,
thanks, that was the issue. I got distracted from too much debugging, when I hunted down Usergrid username/password instead of Cassandra Username/Password. This way I overlooked the error in simply copying the config file from the link that Nate pointed to. One closer look would have sufficed. Thanks for your support anyway.

This is the first request for a connection. Sam makes a good point. Make sure you have the username and password properties set in the configuration file: https://github.com/apache/incubator-usergrid/blob/master/stack/config/src/main/resources/usergrid-default.properties#L52-L53 See this page for details on configuration: http://usergrid.readthedocs.org/en/latest/deploy-local.html#install-and-configure-cassandra For Usergrid specific questions, feel free to stop by our mail list or IRC channel both of which are listed here: http://usergrid.incubator.apache.org/community/ -- ----------------- Nate McCall Austin, TX @zznate Co-Founder & Sr. Technical Consultant Apache Cassandra Consulting http://www.thelastpickle.com
