Zookeeper a good fit?

Currently we have a cluster of machines running a single application. The
cluster performs various background tasks and we have a hacky, home-grown
solution for the nodes in the cluster to coordinate with each other to
perform these background tasks. It's very error-prone and we're looking to
replace it. Would Zookeeper be a good fit for coordinating something like
this? If so, are there any lightweight examples out there we could look at
it?

Thanks very much!
