Hi,
            How to set the maximum number of containers to be executed in
each node.
            So that at a time only that much of containers will be running
in that node..

>From what I know the number of containers will depend on the amount of
resources your node has. If it has 8 Gb RAM and each container has 2 Gb,
then there'll be a maximum of 4 containers.

You can use yarn.nodemanager.resource.memory-mb to set the limit on
each NodeManager.

You should have a good look at
http://hadoop.apache.org/common/docs/r0.23.0/hadoop-yarn/hadoop-yarn-site/ClusterSetup.html
. It has enough information to get you a good distance.
