How to decide the next HMaster?
Could someone explain me which it's the process to select the next
HMaster when the current one is gone down?? I've been looking for
information about it in the documentation, but, I haven't found anything.

This is the recipe how simple ZK-based leader election goes.

But, it's the first which responses to Zookeeper or which creates the
znode? I don't know how it works exactly this process, where could I
read more about it?
