Subject Hadoop Pi Example in Yarn
Date Wed, 18 Dec 2013 20:45:38 GMT
How does the PI example can determine the number of mappers?
I thought the only way to determine number of mappers is via the amount of filesplits you
have in the input file...
So for instance if the input size is 100MB and filesplit size is 20MB then I would expect
to have 100/20 = 5 map tasks.
