hive CLI shell use of `dirname "$0"` prevents it from being linked from other directories

I tried making /usr/bin/hive a link to /usr/lib/hive-0.14/bin/hive . But the launch fails because:

bin=`dirname "$0"`
bin=`cd "$bin"; pwd`
. "$bin"/hive-config.sh

So I used a readlink -f first, to locate the proper script home, and then it works fine.
