>
> when a outstanding request is escalated, the new container request, which has
> relaxed placement and a changed priority (the same node as the original one)
> will be sent.
> because of relaxed placement, RM can allocate a container to a node which
> didn't specify in container request.
> but, it is determined whether a outstanding request has been allocated only
> when the node in the allocated container is the same as the node in the
> outstanding request.
> as a result, it will be failed to track the outstanding request, and Slider
> AM will keep the request which has already been allocated.
> hear is Slider AM log when I met this problem.
