Kasper Sørensen updated METAMODEL-220:
--------------------------------------
    Description: 
We should offer a way to use other scheme's than "hdfs" for Hadoop FileSystem 
based resources.

NOTE: This issue is blocked by/dependent on METAMODEL-219 because the file 
system configuration would need to be loaded from configuration files.

I have heard of at least a few variants that supposedly support the same API:

 * OpenStack Swift (swift://...)
 * Amazon EMR FS (emrfs://...)
 * MapR file system (maprfs://...)

And there are probably more.

Today "hdfs://" is hardcoded into HdfsResource and clearly it should be a field 
which the user can select a different value for. I suggest to keep it simply as 
a string and to also add a couple of constants in the class to make it easy for 
users to pick between the usual candidates.
