Gabriel Reid created CRUNCH-23:
----------------------------------
Summary: PCollection#sort doesn't do a full sort on values
Key: CRUNCH-23
URL: https://issues.apache.org/jira/browse/CRUNCH-23
Project: Crunch
Issue Type: Bug
Reporter: Gabriel Reid
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.
