I'd prefer not doing a naming hack like that directly in HDFS or in FileSystem.
But I don't mind doing it in a layered filesystem, perhaps something like:
har://hdfs-host:port/dir/my.har/file/in/har
So the "har" FileSystem could pull the nested scheme off the front of the host,
and scan the path for a ".har", parse the index there (caching it, presumably),
and finally access the file. In the above case, the har path would be
hdfs://host:port/dir/my.har. No changes to FileSystem or HDFS are required.
That's not too ugly, is it?
