> As part of HADOOP-9902, java execution across many different shell bits were consolidated
down to (effectively) two routines.  Prior to calling those two routines, the CLASSPATH is
exported.  This export should really be getting handled in the exec function and not in the
individual shell bits.
> Additionally, it would be good if there was:
> {code}
> echo ${CLASSPATH} > /dev/null
> {code}
> so that bash -x would show the content of the classpath or even a '--debug classpath'
option that would echo the classpath to the screen prior to java exec to help with debugging.
