Hi,
Ive read that the intermediate map output is written to the disk at the
regular intervals. Infact Ive read that there are background threads which
spill the data onto disk whenever it crosses the threshold.[Source:Hadoop:
The Definitive Guide.]
Ive tried to dig into the code a couple of times

Hi,
Is there any research currently going on where map reduce is applied to
nodes in normal internet scenarios?.In environments where network bandwidth
is at premium what are the tweaks applied to hadoop?
I would be very thankful if you can post me links in this direction.

Hi,
while working on hadoop I realised the need for a benchmarking software to
compare various nodes.
Can you let me know some popular benchmarking programs which are used to
compare cpus.

Hi,
Am trying to implement a small map reduce framework on another file system.
A very elementary one at that.
So I am trying to access the Hadoop source code for that.
Where do I find it?
