Panayotis, I've not seen this happen yet. I've regularly used MO to write my files and both TextFileO/F and NullO/F have worked fine despite me not writing a byte to their collectors. In fact, the test case for MO too passes when I modify it to never emit to the default output sink.
Are you using the default OutputCommitter (FileOutputCommitter)? 2011/5/30 Panayotis Antonopoulos <antonopoulos...@hotmail.com>: > Hello, > I just noticed that the files that are created using MultipleOutputs remain > in the temporary folder into attempt sub-folders when there is no normal > output (using context.write(...)). > > Has anyone else noticed that? > Is there any way to change that and make the files appear in the output > directory? > > Thank you in advance! > Panagiotis. > -- Harsh J
