Colin Patrick McCabe commented on HADOOP-10446:
-----------------------------------------------

Object references are a good consideration.  I remember using that a lot in HA 
namenode configurations for HDFS.

I don't think serializing a config and sending it over the wire is something we 
really need to support in the native client.  The HDFS client doesn't do that, 
so we can implement that feature if and when we need it.  Similarly, Java 
system properties are something I know we don't have to support in C :)

> We need to have a way to read Hadoop configuration XML files in the native 
> HDFS and YARN clients.  This will allow those clients to discover the 
> locations of NameNodes, YARN daemons, and other configuration settings, etc. 
> etc.
