> 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).
