Hi all:
I'm a fresh man to Zookeeper. Finding that the documents at
zookeeper.hadoop.apache.org are mostly about Java client API. However, I

insight on where to look;
Patrick,
Thanks enormously.
This hasn't helped yet, but that is just because it was a very large bite of
the apple. Once I digest it, I can tell that it will be very helpful.
I did have a chance to look at the stat output and maximum latency was
300ms. How that connects with what you are
Well that's good - 300ms max latency means that the server can round
trip any requests pretty quickly. It would lead me to look at the client
VMs or (intermittent) network problems...
Keep in mind though that's one of your servers (unless you are saying
you checked all X of the servers in the
