stack commented on HBASE-2195:
------------------------------
bq. 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.
Thats unfortunate. Yeah, replace the hyphen with an underscore or something
(the UUID toString is no help here).
bq. I am not aware of any length limits for ZNode names, is that correct?
Can you find any in zk apis? I don't know if there are limits. If you can't
figure it, we can ask the lads.
bq. on http://hbase.apache.org/replication.html
Bug J-D on Tuesday after he gets back from holidays. He did a presentation on
it recently; that might be more up-to-date than whats on website.. he'd know
best.
