Sandy Ryza updated YARN-752:
----------------------------
Description: A ContainerRequest that includes node-level requests must also
include matching rack-level requests for the racks that those nodes are on.
When a node is present without its rack, it makes sense for the client to
automatically add the node's rack. (was: A ContainerRequest that includes
node-level requests must also include matching rack-level requests for the
racks that those nodes are on. At the very least, an exception should be
thrown if one is constructed with a non-empty set of nodes but an empty set of
racks.
If possible, it would also be nice to validate that the given nodes are on the
racks that are given. Although if that is possible, then it might be even
better to just automatically fill in racks for nodes.)
> In AMRMClient, automatically add corresponding rack requests for requested
