Hi,

I've found MRUnit a very easy to unit test jobs, is it possible as well to
test mappers reading data from DisributedCache? If yes, can you share an
example how the test' setup() should look like?

Thanks.

Hi,

Not sure how to do it using MRUnit, but should be possible to do this using
a mocking framework like Mockito or EasyMock. In a mapper (or reducer),
you'd use the Context classes to get the DistributedCache files. By mocking
these to return what you want, you could potentially run a true unit test.

Thanks
