Robert Joseph Evans commented on MAPREDUCE-2102:
------------------------------------------------
I am not sure how to do this on other operating systems. On Linux if Hadoop is
running on a newer Kernel then it can use /proc/<PID>/io, but I believe that it
has to be newer then 2.6.20. Anything else would require a very ugly hack like
LD_PRELOAD.
