> I'm gathering all kudu metrics for analytics by using the "/metrics" endpoins on all master/tablet servers. I'm getting the list of tablet-servers by querying "/dump-entites" on a master server.
> "/dump-entites" has top level key for "tablet_servers", but it doesn't contain any information about the other masters. For this, I have to maintain a list of master http adresses and server UUIDs in my solution, and update it there are changes to the masters.
> If the information would be available here, knowing the http address of any working master would give me the list of configured masters, which I could contact for metrics and save for future use.
> (https://github.com/apache/kudu/blob/master/src/kudu/master/master_path_handlers.cc#L777)
> This Jira is a request to add a key like "master_servers"  to the "/dump-entites" endpoint with the information about the other masters, like we have now in "tablet_servers" for the tablet servers.
