How to get the IP of current leader master from the quorum?

Question

Is there any way to get the IP of current leading Mesos-master from the quorum? Does any variable stores that value?

Answer 1

yes. Master information stored in zk as json format. You could get the leader master from zk. Please refer to this article http://codetrips.com/2015/08/16/apache-mesos-leader-master-discovery-using-zookeeper-part-2/ to see how to get it. Macro is the author of add Mesos master json format to zk. You could use the libray https://github.com/massenz/zk-mesos to get leader maste from zk directly.

Answer 2

You can also query the http://{any mesos master}/master/redirect endpoint and parse the current leading master's IP address out of the Location header that is returned.
