Review comment:
I'm little bit concerned about this. We should probably have more registrars
for different schemas. At least for `webhdfs`, which is commonly used.

> _HadoopFileSystem_ creates underlying _FileSystem_ (one from
> org.apache.hadoop) instance during it's construction. Single _FileSystem_
> instance is tied to a particular cluster (scheme + authority pair). In case
> we want to talk to another cluster, this fail due to _FileSystem#checkPath_.
>
> This can be fixed by using _FileSystem#get(java.net.URI,
> org.apache.hadoop.conf.Configuration)_ instead of
> _FileSystem#newInstance(org.apache.hadoop.conf.Configuration)_{{}}
