Description
Currently, YarnAllocator may put a node with a completed container whose exit status is not one of SUCCESS, PREEMPTED, KILLED_EXCEEDED_VMEM, KILLED_EXCEEDED_PMEM into blacklist. Howerver, for other exit status, e.g. KILLED_BY_RESOURCEMANAGER, Yarn do not consider its related nodes shoule be added into blacklist(see YARN's explaination for detail https://github.com/apache/hadoop/blob/228156cfd1b474988bc4fedfbf7edddc87db41e3/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-common/src/main/java/org/apache/hadoop/yarn/util/Apps.java#L273). So, relaxing the current blacklist rule and having the same blacklist behaviour with YARN would maxmize use of cluster resources.
