I am copying/pasting the answer I provided to this same question that you asked on StackOverflow. You could either implement your own ActiveMQ message store (http://activemq.apache.org/maven/5.3.1/activemq-core/apidocs/org/apache/activemq/store/package-summary.html) for HDFS which would allow ActiveMQ to use HDFS as a persistence store, or you could create an ActiveMQ broker plugin (http://activemq.apache.org/interceptors.html) which would allow you to intercept messages as they enter the broker. Both are very different approaches, so it really depends on your requirements as to which path to take.
