Lars George commented on HBASE-1329:
------------------------------------

Could we please collect a list here of what information should be made visible out of the ZK data? Also where, i.e. UI or shell and what commands should be added to either of them to change ZK values?

> Currently, to the users of HBase ZooKeeper is some mysterious thing that is for some reason important but no one knows why. We need to provide more visibility into ZooKeeper from HBase.
> This issue is to start a discussion on what sorts of things we can/should provide. Some possible ideas to get started:
> - Running a REST server. See ZOOKEEPER-36.
> - FUSE support. See ZOOKEEPER-25.
> - Admin/surgery tools in HBase shell. Answer questions like "in safe mode?"
> - Status and information on HBase's data in ZooKeeper in the web UI.
