Subject Hadoop on different hardware
Date Sun, 15 Jul 2007 09:16:40 GMT

I'm wondering how does work hadoop on a cluster of few machine with
different hardware.

For instance, i have a cluster of 2 machine with the same hardware (same CPU
p4 2.8 , same memory RAM 2Go).
I've configured hadoop to use 1Go of memory for the MapReduce process, with
2 tasktracker child of 400 Mo.

I would like to add another machine which is an AMD Athlon with only 512Mo
of RAM.
is it possible to do it ? is there any script to change to limit the number
of process to run on this machine to have only 1 tasktracker of 400Mo
running on this machine ?

if not, does it mean that we need to have the same size of RAM on each
machine ?
