TaskTracker without datanode

Hi All,

I was wondering (network traffic considerations aside) is it possible to run a TaskTracker without a DataNode. I was hoping to test this method as a means of scaling processing power temporarily.

Are there better approaches, I don't (currently) need the additional storage that a DataNode provides and I would like to add additional processing power from time-to-timewithout worrying about data loss and decommissioning DataNodes.

Thanks, Dan.
