Hi all
Pig Latin script we write is converted to number of map reduce jobs to be
executed by Hadoop.
So my assumption was that if we write number of lines in Pig Latin, it will
generate a equivalent Map reduce program as in Java. But while debugging
the source code, I could not find anything of that sort .
In what way jobs are submitted to Hadoop? I want to know how Pig
communicates with Hadoop framework and get the jobs done. i was unable to
find this thing. It will help me greatly in my college project.
Thanks and regards,
