> Right now changing the default file system does not work with the HDP 2.0.6+ stacks.
Given that it might be common to run HDP against some other file system in the cloud, adding
support for this will be super useful. One alternative is to consider a separate stack definition
for other file systems, however, given that I noticed just 2 minor bugs needed to support
this, I would rather extend on the existing code.
> Bugs:
>  - One issue is in Nagios install scripts, where it is assumed that fs.defaultFS has
the namenode port number.
>  - Another issue is in HDFS install scripts, where {{hadoop dfsadmin}} command only works
when hdfs is the default file system.
> Fix for both places is to extract the namenode address/port from {{dfs.namenode.rpc-address}}
if one is defined and use it instead of relying on {{fs.defaultFS}}. 
> Haven't included any tests yet (my first Ambari patch, not sure what is appropriate,
so please comment).
