Changing Hadoop Niceness

We have a staging environment where the NameNode shares a machine with a
DataNode and TaskTracker.

Can anyone suggest a way to set different hadoop-env.sh values for DataNode
and TaskTracker without having to duplicate the whole Hadoop conf directory?
For example, to set a different HADOOP_NICENESS for the DataNode and
TaskTracker, but not for the NameNode.

TIA
