Multiple dataframe outputs from the same reducer

[SudipSinha]

Hi,

I want to emit two types of data frames (having different dimensions and column names) out of the reducer. On one of the data.frames, the keys have to be repeated. Let us assume that these are the 'iris' and the 'mtcars' datasets. I want the key of the mtcars dataset to be 'mpg' column and that of the iris to be the 'Species' column (this is with repetition as there are only 3 values).

I want to use the the output of the first MapReduce as the input to the second MapReduce, only for the case where the keys are repeated.

Can this be done in rmr2?

Regards,
Sudip
