Add explicit remote map count JobTracker metrics
------------------------------------------------
Key: HADOOP-5755
URL: https://issues.apache.org/jira/browse/HADOOP-5755
Project: Hadoop Core
Issue Type: Improvement
Components: mapred
Reporter: Hong Tang
I am proposing to add a counter REMOTE_MAPS in addition to the following
counters: TOTAL_MAPS, DATA_LOCAL_MAPS, RACK_LOCAL_MAPS. A Map Task is
considered a "remote-map" iff the input split returns a set of locations, but
none is chosen to execute the map task.
