Mostafa Elhemali updated HDFS-4320:
-----------------------------------

    Attachment: HDFS-4320.branch-1.3.patch

Thanks Suresh - updated the patch with unit test and documentation in 
hdfs-default. This is the documentation I have - does it sound good?

{code}
<property>
  <name>dfs.namenode.rpc-address</name>
  <value></value>
  <description>
    RPC address that handles all clients requests. If empty then we'll get the
    value from fs.default.name.
    The value of this property will take the form of hdfs://nn-host1:rpc-port.

> When NameNode starts up, it tries to find out its address by looking at the 
> fs.default.name configuration key instead of using its own keys. This breaks 
> scenarios where we try to configure a Hadoop cluster that uses a different 
> default file system than DFS, but still try to prop up namenode and datanode 
> services as a secondary file system.
