-RE: On a small cluster can we double up namenode/master with tasktrackers?
Good points all,
The mapreduce jobs are, well. intensive. We've got a whole variety, but
typically I see them use a lot of CPU, a lot of Disk, and upon occasion a
whole bunch of Network bandwidth. Duh right? J
The master node is mostly CPU intensive right? We're using LXC to segregate
(psudo-virtualize) our environments for ease of development and management.
I'm looking into whether I can use LXC's quota system to guarantee a certain
level of CPU resources to the container where the master node is housed. If
I can do that I guess we wouldn't have any issue here.

You didn't look at how resource intensive your map/reduce jobs are.
