Attachment: HADOOP-7984.patch
Attaching a patch to add "--loglevel" option. I verified it worked on Linux. However, I have
not tried it on Windows yet since I don't have Windows environment.

> It would be helpful if bin/hadoop had verbose and debug flags. Currently users need to
set an env variable or prefix the command (eg "HADOOP_ROOT_LOGGER=DEBUG,console hadoop distcp")
which isn't very user friendly. We currently log INFO by default. How about we only log ERROR
and WARN by default, then -verbose triggers INFO and -debug triggers DEBUG?
