stack commented on HBASE-5573:
------------------------------
Patch makes sense. No need of copyright line above license when you create
next version of patch. ZKHBaseNodes needs javadoc.
Should this be in ZKUtils and not in ROZK?
{code}
+ // Used by ZKUtil:waitForZKConnectionIfAuthenticating to wait for SASL
+ // negotiation to complete
+ public CountDownLatch saslLatch = new CountDownLatch(1);
{code}
I see. ROZK has a RZK. Can RZK have a ZooKeeper only?
Looks good. Looks like hard work.

> Some code in the package needs to read data in ZK. This could be done by a
> simple read, but is actually implemented with a watcher. This holds ZK
> resources.
> Fixing this could also be an opportunity to remove the need for the client to
> provide the master address and port.
