empty? i.e. you created a new zk, or did you create some znodes in
this directory prior to running the "ls /"?

I see that you're connecting the client to localhost:2181, what does
the configuration of the three servers look like? (can you attach

We have seen some issues with 3.4.4 on jdk7, but I don't think that's
the same thing here. You might try using 3.4.3 or jdk6 instead to see
