Yuan LUO updated MAPREDUCE-7227:
--------------------------------
Description:
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. So we can modify
AppMaster through client's ‘default.FS’ to create job staging dir.
