Subject Change Map-Red Parameters
Date Fri, 18 Mar 2011 04:33:55 GMT
Dear all,

Is it possible in Hadoop Map-Reduce Framework to change the job 
execution parameters during runtime.

I know we can set through job.setNumTasks and many parameters but this 
remains only for that job. In Hadoop Pipes we can set it through -D 
parameter. But the problem is other.

What I want is to run a MAp-Reduce program that changes the 
mapred-site.xml parameters and the changes got reflected in the next jobs.

Please guide me if there is a way to do this.

Thanks & best Regards
Adarsh Sharma
