The AM gets this information from RM via the return value for AMRMProtocol.registerApplicationMaster.

What could be the minimum size.Because my cluster size is 2.5GB
When i set 100 mb for each container only 2 instances are launched in each
node.
When i set 1000 mb for each container even then 2 instances are launched in
each node.
What could be the problem.

Sorry for the cross posting...

The default is 1000MB.

Try bumping down yarn.scheduler.fifo.minimum-allocation-mb to 100 (default is 1024) for FifoScheduler or  yarn.scheduler.capacity.minimum-allocation-mb for CapacityScheduler.

Sorry, wasn't clear - default is 1024 for both schedulers. Use those configs to tune them.
