Work Description: angoenka commented on issue #6251: [BEAM-5180] Relax
back restriction on parsing file scheme
URL: https://github.com/apache/beam/pull/6251#issuecomment-415830568
From the java.net.URI docs,
A hierarchical URI is subject to further parsing according to the syntax
`[scheme:][//authority][path][?query][#fragment]`
Which enforces //
But to support HDFS and unblock our selves we should go with the rollback.

> introduced more strict schema parsing which is breaking the contract between
> _FileResultCoder_ and _FileSystems.matchNewResource()_.
> Coder takes _ResourceId_ and serialize it via `_toString_` methods and then
> relies on filesystem being able to parse it back again. Having strict
> _scheme://_ breaks this at least for Hadoop filesystem which use _URI_ for
> _ResourceId_ and produce _toString()_ in form of `_hdfs:/some/path_`
> I guess the _ResourceIdCoder_ is suffering the same problem.
