     [ https://issues.apache.org/jira/browse/YARN-10395?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

chan updated YARN-10395:
------------------------
    Description: 
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.
