------------------------------------
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.
