Subject Re: Thrift on regionservers - won't connect
Date Thu, 09 Feb 2012 19:43:12 GMT
60010 is the web ui port by default, 60000 is the port the master uses
for communication. Clients (like thrift) and region servers don't rely
on a configured port because the master already posts it in zookeeper
along with its address (that's how your thrift server found it).

If your region servers are using master:60000 and they don't have any
problem connecting to a port that doesn't respond, we have a bigger
issue here :)
