linux containers with Hadoop

[bikash sharma <sh...@gmail.com>]

Hi,
Does anyone knows if Linux containers (which are like kernel supported
virtualization technique for providing resource isolation across
process/appication) have ever been used with Hadoop to provide resource
isolation for map/reduce tasks?
If yes, what could be the up/down sides of such approach and how feasible it
is in the context of Hadoop?
Any pointers if any in terms of papers, etc would be useful.

Thanks,
Bikash

Thanks Edward, so mostly the linux containers are used in Hadoop for
ensuring isolation in terms of providing security across mapreduce jobs from
different users (even mesos seem to leverage the same) not for resource
fairness?

Previously hadoop launched map reduce tasks as a single user, now with
security tasks can launch as different users in the same OS/VM. I would say
the closest you can to that isolation is the work done with mesos .
