Hello @Brender and @Rad, @Brender, we know about mesos-cassandra, but it says that it isnt production ready:
"*DISCLAIMER* *This is a very early version of Cassandra-Mesos framework. This document, code behavior, and anything else may change without notice and/or break older installations."* And we will use it in production, then we think that its better to hand craft the configuration (because we can config like we need) instead of use something that could change soon and we don't have much control. @Rad, Thank you, It will help a lot.
