Subject How can a task know if its running as a MR1 or MR2 job?
Date Tue, 03 Jun 2014 12:04:05 GMT
Just a quick question... 

Suppose you have a M/R job running. 
How does the Mapper or Reducer task know or find out if its running as a M/R 1 or M/R 2 job?


I would suspect the job context would hold that information... but on first glance I didn't
see it. 
So what am I missing? 

Thx

-Mike
