Subject: TaskTracker without datanode

Hi All,

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

Are there better approaches, I don't (currently) need the additional storag=
e that a DataNode provides and I would like to add additional processing po=
wer from time-to-timewithout worrying about data loss and decommissioning D=
ataNodes.

Thanks, Dan.
