Subject How reduce tasks know which partition they should read?
Date Mon, 09 Mar 2015 14:56:23 GMT
Hi,

I am looking to the Yarn mapreduce internals to try to understand how 
reduce tasks know which partition of the map output they should read. 
Even, when they re-execute after a crash?

I am also looking to the mapreduce source code. Is there any class that 
I should look to try to understand this question?

Any help?

Thanks
