Hi, On this page
http://www.datastax.com/documentation/cassandra/2.0/cassandra/install/installJnaRHEL.html it says "Cassandra requires JNA 3.2.7 or later. Some Yum repositories may provide earlier versions" and at the bottom "If you can't install using Yum or it provides a version of the JNA earlier than 3.2.7, install as described in Installing the JNA from the JAR file." Which version of OS and Cassandra are you running? thanks, Garret On Wed, Feb 25, 2015 at 10:46 AM, J.
