Subject Re: Setup/Cleanup question
Date Sat, 23 Mar 2013 03:40:23 GMT
When running an MR job/program assuming there r 'n' (=100) Mapperstriggered then my question
is will the setup & cleanup run n number of times which means once for each mapper or
for all the mappers they will run only once. 

Any help is appreciated.
