I am using hadoop 1.2.1 to develop mapreduce programs. I look in hadoop 1.2.1 many of them or in general use JobConf Object to operate the driver class. And then I need waitforcompletition function that belongs to Job Object.

So should I use 2 object's JobConf and Job in one driver class? or I just use only Job ? Or how?

  • thanks bro firstly for your answer, it's true if jobConf is old and job is new. So I use the old one, because I need it's distributed cache feature that use jobConf. So in your opinnion, how can I create wait for completion or anything with the same function with jobConf? Thanks bro, I need your suggest.... – Kenny Bi Feb 22 '15 at 16:16
