> LeaderElector.checkIfIAmLeader checks to see if it has duplicate registrations in under its election node, but it does this by prefix checking, which means that if core_node1 registers itself after core_node11, it will think it's a duplicate, and delete the core_node11 node.
> This is causing regular failures in UnloadDistributedZkTest.
