> Issue Type: Bug
> Reporter: Amar Kamat
>
> _hostnameToNodeMap_ maintains a map from _hostname_ to _resolved-address_.
> {{JobTracker.addNewTracker()}} resolves a node's address if the node is not
> present in _hostnameToNodeMap_ but uses _tracker-name_ to index into
> _hostnameToNodeMap_ instead of _hostname_.
