Hi,
I was running a map reduce job in a demo cluster with 3 Data node ,1
Jobtracker and 1 NameNode. But the Data node specified are not working
except the Data node in the Name Node when i look in to the web interface
for the Name Node.
And it seems slower than the same job runs in a single node. What can i
do....
Will the Data Node specified wo'nt work if the data is not so large?????
