Subject question about scheduler rack awareness
Date Tue, 19 Mar 2013 07:30:05 GMT

I have a question about the scheduler rack awareness:

if each map task handles several blocks once, how the map task will be
created ?

for example, if I have a file with 100 blocks, tends to use 10 map task to
do wordCount.

my question is : will the map task created on the node which access his 10
blocks most fastest ?

thanks a lot
