Our yarn cluster is made up of some independent hdfs cluster, the 'default.FS' in every hdfs cluster is different.when user submit job to yarn cluster,if the 'default.FS'  between client and nodemanager  is inconsistent,then the job-staging dir  can't be cleanup by AppMaster.Because it will produce two job-staging dir in our conditions by client and appmaster.
