Description

hadoop jar myjar.jar MyDriver -fs file:/// -jt local input.txt output/
should run a job using the local file system and the local job runner. Instead it tries to connect to a jobtracker.

hadoop jar myjar.jar MyDriver -fs file:/// -jt host:port input.txt output/
does not use the given host/port

This appears to be because Cluster#initialize, which loads the ClientProtocol, contains no special handling for mapred.job.tracker.
