Hadoop processing
Hadoopers,
“Hadoop ships the code to the data instead of sending the data to the code.”
Say you added two DNs/TTs to the cluster. They have no data at this point, i.e. you have not ran the balancer.
In view of the above quoted statement, will these two nodes not participate in the MapReduce job until you balanced some data onto those nodes? Please kindly elaborate.

Rgds,
