[jira] [Created] (HADOOP-15774) Discovery of HA servers

Íñigo Goiri created HADOOP-15774:
------------------------------------

             Summary: Discovery of HA servers
                 Key: HADOOP-15774
                 URL: https://issues.apache.org/jira/browse/HADOOP-15774
             Project: Hadoop Common
          Issue Type: New Feature
            Reporter: Íñigo Goiri


Currently, Hadoop relies on configuration files to specify the servers.
This requires maintaining these configuration files and propagating the changes.
Hadoop should have a framework to provide discovery.
For example, in HDFS, we could define the Namenodes in a shared location and the DNs would use the framework to find the Namenodes.
