As per 
[comment|https://issues.apache.org/jira/browse/YARN-4852?focusedCommentId=15209689&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15209689]
 from [~sharadag], there should be safe guard for duplicated container status 
in RMNodeImpl before creating UpdatedContainerInfo. Or else in heavily loaded 
cluster, if any duplicated container are sent to RM(may be bug in NM also), RM 
should not create UpdatedContainerInfo for duplicated containers. 
This is an optimization for issue kind YARN-4852
