Subject [jira] [Commented] (HADOOP-8087) Paths that start with a double slash cause "No filesystem for scheme: null" errors

Colin Patrick McCabe commented on HADOOP-8087:
----------------------------------------------

Wow, this is an oldie (and not goodie).

I agree that we should fix this in 2.x.  It should be a compatible change.

> {{Path}} is incorrectly parsing {{//dir/path}} in a very unexpected way.  While it should
translate to the directory {{$fs.default.name}/dir/path}}, it instead discards the {{//dir}}
and returns
> {{$fs.default.name/path}}.  The problem is {{Path}} is trying to parsing an authority
even when a scheme is not present.
