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
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 ?
