[jira] [Commented] (HADOOP-8087) Path parsing is flawed

["Doug Cutting (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-8087?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13210604#comment-13210604 ] 

Doug Cutting commented on HADOOP-8087:
--------------------------------------

Paths are a subset of URIs.  A relative URI permits an authority even when a scheme is not present.

I'd expect "//foo/bar" to be interpreted as "${defaultScheme}//foo/bar".

> {{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.
