A big positive vote for Zookeeper.
The most salient aspect of my experience using zookeeper is that

Hi
Apple provides opensource discovery service called Bonjour (zeroconf). Is it
possible to integrate Zeroconf with Hadoop so that discovery of nodes become
automatic ? Presently for setting up multi-node cluster we need to add IPs
manually. Integrating it with bonjour can make this process automat
