> testHDFSConf.xml uses a regex to describe username. Regexes are used 
> incosistently from {code}[a-zA-z0-9]*{code} to {code}[a-z]*{code}. Clearly OS 
> are less restrictive than that, and for us specifically the test fails for a 
> build user having a {{-}}. So instead of keeping updating regex, I propose to 
> replace it with the macro USERNAME.
