Hadoop related software used to deploy in isolated directory and use
environment variables to drive the location of the software. GNU layout of
single prefix does not work for tarball deployment because there are prefix
directory per service. This is the reason that --hadoop-home, --hbase-home are
implemented instead of --prefix.
This is both useful for beginner or for script automation. I will include some
documents for HBase book or HBase site.

Existing tarball deployment does not have a default location, hence, the
default is set to /usr for rpm/debian package default location. I will added a
check for /usr/bin/hadoop and bail out if hadoop does not exist.

Good catch, I will make defaults for those two properties. How about default
HBASE_LOG_DIR to ${HBASE_HOME}/var/log and ${HBASE_HOME}/var/run for
consistency?

I will make the change to exclude the year. Thanks :)
