> 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.
