JobConf.get("mapred.task.id") gives you everything (including attempt id).

主   题: Reducer ID

Hello,

Is it possible to know the unique id of a reducer inside the reduce or setup
method of a reducer class? I tried to find any method of the context class
which might help in this regard but could not get any.

Thanks,
Farhan
