Re: Does the class of the Mapper output need to match the exact class
of the specified output?
Hello
I have been working on counters for the jobs.
I did get all the counters for jobs . but i do require to show all the
counters in my own UI. i am using webservices to show all the counters.
Could someone help me with this..?
or is there any other way to get thecounters
My approach :-
i use reporter.incrcounter method to get the counters increment.
and run another program to read all the counters
Regards,
Rajan

You can get them through JobTracker object. Where the other program is
running?
