I could get containers on specific nodes using addContainerRequest() on AMRMClient. But there are issues with it. I have two nodes, node1 and node2 in my cluster. And, my Application Master is trying to get 3 containers on node1, and 3 containers on node2 in that order.
While trying to request on node1, it sometimes gives me those on node2, and vice verse. When I get a container on a different node than the one I need, I release it and make a fresh request. I am having to do like that forever to get a container on the node I need. Though the node I am requesting has enough resources, why does it keep giving me containers on the other node? How can I make sure I get a container on the node I want? Note: I am using the default scheduler, i.e. Capacity Scheduler.
