This will break users in two ways:

1. Many user scripts use $HADOOP_HOME/bin/X to find script X.
2. Until those scripts are available in other locations, there is no
choice. For users that want to manage the servers manually, having
access to the hadoop-daemon.sh is required. Of course, it should be in
/usr/sbin/hadoop-daemon.sh, but until it is of course the users needs
to reference it in $HADOOP_HOME/sbin/hadoop-daemon.sh.
