hbase-config.sh not using the right pid file

I've actually posted to the mailing list about this already and decided to open a ticket in the meantime: https://groups.google.com/a/cloudera.org/group/cdh-user/browse_thread/thread/2d9065695cde385a

The short version is that the hbase-config.sh defaults to using '/tmp' as the pid directory while the init scripts packaged with CDH3 are sourcing '/etc/defaults/hbase' which puts the pid files under '/var/run/hase'. This causes scripts such a '/usr/lib/hbase/bin/graceful_stop.sh' to not function since it's looking in the wrong place for the pid file.

One fix is to source the '/etc/defaults/hbase' file in the '/usr/lib/hbase/bin/hbase-config.sh' script as shown here – http://paste.org/48352
