We want to include Cassandra into Fedora, and there are some tweaks to cassandra sources we need to do. The io.airlift:airline dependency is one of those tweak we gotta do. Cassandra depends on arline 0.6, but In Fedora we have the latest upstream version 0.7. It was released quite time ago on Nov 6 2014. I attached a patch updating cassandra sources to depend on the newest airline sources. The only actual changes are in the imports. Please consider updating.
