+(1) solves the hanging problem on map side with empty input and nonempty output — this map task generates output properly to intermediate files similar to other map tasks.
+(2) solves the problem of hanging reducer with empty input to reduce task and nonempty output — this reduce task doesn't generate output if input to reduce task is empty.

+
+Added a new conf property dfs.namenode.decommission.nodes.per.interval so that NameNode checks decommission status of x nodes for every y seconds, where x is the value of dfs.namenode.decommission.nodes.per.interval and y is the value of dfs.namenode.decommission.interval.
