> How do we know what parts are the filename?
Could we assume the URIs are hierarchical URIs (defined in the
[java.net.URI|http://java.sun.com/javase/6/docs/api/java/net/URI.html])? If
yes and we further force the rule that scheme must be specified with authority,
then the syntax will be
[[scheme:]//authority]path
I think the colons can be distinguished in this case.
I agree that the current patch is simple and clean. However, users cannot
perform something like
{code}
> ls
a:b foo
> bin/hadoop fs -put a* baz
{code}

> Path(String pathString) when given a filename which contains ':' treats it as
> URI and selects anything before ':' as
> scheme, which in this case is clearly not a valid scheme.
