Colin Patrick McCabe commented on HADOOP-10446:
-----------------------------------------------
While that's clever, I don't think that would really be an option for most
people. Most management software just creates XML files for Hadoop. It would
be a lot of work to introduce an extra step where configurations needed to be
compiled to something else.
Reading the configuration looks daunting at first, but you have to remember
that we really only need to support the features the client needs. In fact, I
think things would be simpler if we just had a ConfigurationBuilder type thing
that created immutable Configuration objects. Then a lot of the really
complicated concurrency issues with the Configuration class in Java just go
away in the C version.

> 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.
