All APIs in the deprecated JobConf class are wrappers around the Configuration API that you probably are using in the 20.2 new API. For e.g. : setProfileEnabled = configuration.setBoolean("mapred.task.profile", value) setProfileTaskRange = configuration.set("mapred.task.profile.maps", value) or configuration.set("mapred.task.profile.reduces", value) setProfileParams = configuration.set("mapred.task.profile.params", value) Could you try setting these parameters in the Configuration you might be using for the Job and see if that works ?
