> A patch for a unit test is attached to reproduce the issue. It creates a 
> container request with only racks specified (nodes=null) and relax locality 
> set to false. With the node-locality-delay conf set appropriately, we wait 
> indefinitely for a container allocation and the test will timeout.
> My understanding of what causes this issue is as follows. The 
> RegularContainerAllocator delays a rack local allocation based on the 
> node-locality-delay parameter. This delay is based on missed opportunities. 
> However, the corresponding off-switch request is skipped but does not count 
> towards a missed opportunity (because relax locality is set to false). So the 
> allocator waits indefinitely.
