Subject Help!!The problem about Hadoop
Date Tue, 05 Oct 2010 07:34:34 GMT
Hi, all
I do an application using hadoop.
I take 1GB text data as input the result as follows:
    (1) the cluster of 3 PCs: the time consumed is 1020 seconds.
    (2) the cluster of 4 PCs: the time is about 680 seconds.
But the application before I use Hadoop takes about 280 seconds, so as the speed above, I
must use 8 PCs in order to have the same speed as before. Now the problem: whether it is correct?
