    Description

      JobInProgress.maps[], JobInProgress.reduces[], JobInProgress.setup[] and JobInProgress.cleanup[] are incorrectly synchronized resulting into findbugs warnings. Except the getter apis (i.e getMapTasks(), getReduceTasks(), getSetupTasks() and getCleanupTasks()), these structures are always accessed in synchronized methods.
