-Re: Requesting containers on a specific host
Krishna Kishore Bonagiri 2013-07-04, 10:14
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.
