Description

TaskRunner does hprof specific handling of the mapred.task.profile.params; specifically it assumes the "file=%s" which is hprof specific. It would be nice to generalise it to allow using yourkit and other profilers. Similarly JobClient tries to fetch 'profile.out' which is again hprof specific.
