Steve Loughran updated HADOOP-5687:
-----------------------------------
Status: Patch Available (was: Reopened)
This will fail, but I want everyone to see the messages are fairly useless.
Half the problem is URI.create that turns the UriSyntaxException into a runtime
IllegalArgumentException, which floats up without telling the user why things
went wrong
I propose that, at a minimum, {{FileSystem.getDefaultUri()}} should replace
{{URI.create())} with something that catches the syntax exceptions and says
that fs.default.name is wrong. If someone really has time on their hands, they
could look through all uses of {{URI.create())} outside of the test code and
decide if they should stay. Having had a quick run through, I dont see any that
are as urgent as this one.

> Throwing NPE is confusing; instead, an exception with a useful string
> description could be thrown instead.
