Lars Hofhansl commented on HBASE-2195:
--------------------------------------
Now I have to wrap my head around the naming convention in Zookeeper.
Currently this is all labeled with the 1 digit cluster id.
'-' is used as separator in case of ZK failures.
So the ClusterUUID needs to be encoded (maybe as simple as replacing - with x).
Base64 encoding is no good because it contains / . Or maybe it is simpler to
use ; as separator now.
I am not aware of any length limits for ZNode names, is that correct?
Is the description here http://hbase.apache.org/replication.html, still
completely up-to-date?
