Books only in SecondarySortBookSort #4

Closed matthieu-vergne closed 11 years ago

Hi,

I am trying to implement the secondary sort for the last exercise, but in the mapper I get only book tuples, not the authors. From what I understood, I should get both of them, like in the basic exercise, but emit them in a specific way using the available classes. Did I misunderstood something?

don't use the class SecondarySortBookSort, its an artifact from an old assignment, that we took out of the class.

OK
