Subject Setting Number of Mappers and Reducers in DistributedRowMatrix Jobs
Date Fri, 11 Jun 2010 16:07:30 GMT
Hi everyone,

I am running code that uses some of the jobs defined in the
DistributedRowMatrix class and would like to know if I can define the number
of mappers and reducers that they use when running?  In particular, with the

- MatrixMultiplicationJob
- TransposeJob

I am happy to comfortable with changing the code to get this to work but I
was wondering if the algorithmic logic being employed would allow multiple
mappers and reducers.
