> 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.
