So after more investigation, URI, which is backing the HadoopResourceId does
also drop '//' on empty authority when calling HadoopResourceIr.resolve() and
produce string versions of resource in "hdfs:/path" form. This is not accepted
back as hdfs scheme by FileSystems.matchNewResource(). The question is, what
would be an elegant fix to that.

Is anyone have this problem if it is using HDFS paths in form with vs without
authority? *hdfs:///path/to/dir* vs *hdfs://ha-nn/path/to/dir* ?
I suspect the problem could be drop empty authority here:
[https://github.com/apache/beam/blob/master/sdks/java/io/hadoop-file-system/src/main/java/org/apache/beam/sdk/io/hdfs/HadoopFileSystem.java#L260]
Which does for
{code:java}
FileSystems.matchNewResource("hdfs:///path/to/dir", false)
{code}
produce
{code:java}
hdfs:/path/to/dir
{code}
Reading back such path via FileSystems.matchNewResource() produce a
ResourceId with "file" schema because of the chance in BEAM-5180
