Description

MAPREDUCE-5762 removed mapreduce.jobtracker.staging.root.dir from mapred-default.xml but the property is still being used by LocalJobRunner and the code default value does not match the value that was removed from mapred-default.xml. This broke the use case where multiple users are running local mode jobs on the same node, since they now default to the same directory in /tmp.
