Modified jruby scripts to pick up drainingZNode and masterAddressZNode correctly, from within znodePaths in ZooKeeperWatcher. Modified get-active-master.rb to retrieve server name using MasterAddressTracker instead of ZKUtil. Tested on a standalone HBase deployment to check that the scripts work as expected.
