Description

stack's idea in the design doc for splittable-meta.

We can keep a live list of masters to query by fetching the list of available masters from any of the available masters configured in the seed list. User configured list of masters ("hbase.masters") would be used as a seed list.

The endpoints are refreshed every 5mins or if any of the registry RPCs hit an error (which ever happens first).
