Hi all,
We are studying using ZooKeeper to manage configuration across multiple
processes server. What would be also interesting, as ZooKeeper know the
list of process running, would be to use it to distribute tasks.
We have some long running tasks, so we used multiple servers to process
The general way to do this is either
a) have lots of watchers who all try to create a single file when a watched
file changes. This is very simple to code, but leads to a lot of
notifications when you have thousands of watchers.
b) arrange the watchers in a chain. This is similar to the
Hi David -
As far as I can tell this was not a deliberate omission - earlier versions
of the package definitely had zkCli bundled with. Apologies for the
oversight. Can you fix by copying zkCli.sh from a 3.2.* tarball from the
Apache site?
However, these packages are rather old, and we haven't

You can think of this as a problem with using singleton in a multi-threaded
program. The solution that provides better code readability at affordable
cost should win.
Specifically the problem I am trying to solve is this:
We have a multi-threaded webapp based on a framework (means I am
