      The 'shutdown' znode was renamed 'running'.

      Description

      Right now the node /hbase/shutdown is used to indicate cluster status (cluster up, cluster down).

      However, upon a chat with Lars George today, we feel that having a name /hbase/shutdown is possibly bad. The /hbase/shutdown zknode contains a date when the cluster was started. Now that is difficult to understand and digest, given that a person may connect to zk and try to look at what it is about (they may think it 'shutdown' at that date.).

      I feel a better name may simply be: /hbase/running. Thoughts?
