Rahul Sharma updated CRUNCH-51:
-------------------------------
Attachment: CRUNCH-51.patch
Gabriel, I have fixed the sorting issue. I tried testing for some Avro data as
well and then I made some changes to the RerverseAvroComparator to make it
work. For the materalized issue, can you please check the log that gets
created for the job? I think it should have a clear error of what went wrong.
Most probably it could be like schema not set. Or can you provide me the test
case ? I can try to run it and see the error.
> PCollection#sort relies on using a single reducer for total order sorting

> The total-order sorting provided by the Sort class (and therefore
> PCollection#sort) relies on using a single reducer in order to provide
> total-order sorting. This is very inefficient for large datasets, and should
> be replaced with a total order partitioner instead.
