-------------------------------------
Thanks for looking into this, [~arpitagarwal]! I was not sure whether this
fragment is even needed because it's commented out.

> testHDFSConf.xml uses regexes inconsistently to match the username from
> {code}[a-zA-z0-9]*{code} to {code}[a-z]*{code}. This by far does not cover
> the space of possible OS user names. For us, it fails for a user name
> containing {{'-'}}. Instead of keeping updating regex, we propose to use the
> macro USERNAME.
