Hi all,

Whats the difference between the Job classes present in

o.a.h.mapred.jobcontrol and o.a.h.mapreduce ..

Both have different types of constructors , different functions etc..

Which one should we use in out MR programs..

Thanks

The mapred package was prevalent till the 0.19 versions.. From 0.20 onwards,
we are using the mapreduce package. mapred is deprecated in 0.20 and will be
phased out in the future releases.. So, use the mapreduce package...

Amandeep ,

Thanks for your reply , but i can't find functions such as
"addDependantJob()" etc in mapreduce package,
They are present in mapred.jobcontrol.Job , Are they removed or replaced by
some other functions in 0.20.0

Thanks

Yes there are changes in the api. I'm not sure what's the equivalent
function in this particular case. If you can't find anything, you can
use the mapred package. It'll work fine as of now...

o.a.h.mapred.jobcontrol.Job and mapreduce.Job are two different classes.
o.a.h.mapred.jobcontrol.Job is deprecated and corresponding new api is
available in branch 0.21 @ o.a.h.mapreduce.lib.jobcontrol.ControlledJob.

Thanks
