------------------------------------
Summary: failed to track a outstanding request which was escalated
Key: SLIDER-1104
URL: https://issues.apache.org/jira/browse/SLIDER-1104
Project: Slider
Issue Type: Bug
Affects Versions: Slider 0.81
Reporter: kyungwan nam
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.
