Rahul Sharma commented on CRUNCH-23:
------------------------------------
Gabriel, I check the patch for avro files. It does not work. My bad, should
have verified it earlier. Also while fixing it I am getting stuck at a point.
In the end the TotalOrdePartioner requires a SequenceFile. How can I make one
using the keys from Avro data? Still trying out a few options e.g. configuring
AvroSequenceFileOutputFormat.
> PCollection#sort doesn't do a full sort on values

> When a PCollection is sorted (using PCollection#sort), the sorting that is
> performed is only per reducer, and not an absolute sort over all values. This
> means that the values are not in sorted order if they are iterated over on a
> materialized collection. It also means that the sorted files that are output
> from a sort operation can not be simply concatenated to come to a single
> sorted file.
