Harsh J commented on HBASE-4451:
--------------------------------
Andrew - Agreed. Am not looking to encourage this, btw.
Just that, if its a node without which HBase shuts down, (loosely speaking) the
condition shouldn't look like {{if !shutdown: shutdown()}}, but may look like
{{if !running: shutdown()}} for better maintainability (code-wise).
Would changing this have an effect on compatibility? I'd like to change it, but
would hate to break any things you know would to possibly be monitoring this?

> Project: HBase

> 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?
