> 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.
