> 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?
