> The HS2 tez-site.xml does not change dynamically - the XML parsed components
> of the config can be obtained statically and kept across sessions.
> This allows for the replacing of "new TezConfiguration()" with a HS2 local
> version instead.
> The configuration object however has to reference the right resource file
> (i.e location of tez-site.xml) without reparsing it for each query.
