Project: Hadoop YARN
Issue Type: Bug
Components: capacityscheduler
Affects Versions: 2.9.2

Now,if a app reserved a node,but the node is added to app`s blacklist.
when this node send heartbeat to resourcemanager,the reserved container
allocate fails,it will make this node can not allocate other container even
thought this node have enough memory
or vcores.so i think we can release this reserved container when the reserved
node is in the black list of this app.
