Josh Wills updated CRUNCH-51:
-----------------------------
Affects Version/s: 0.3.0
> PCollection#sort relies on using a single reducer for total order sorting
> -------------------------------------------------------------------------
>
> Key: CRUNCH-51
> URL: https://issues.apache.org/jira/browse/CRUNCH-51
> Project: Crunch
> Issue Type: Improvement
> Affects Versions: 0.3.0
> Reporter: Gabriel Reid
>
> 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.
> For more information, see CRUNCH-23 (and possibly also MAPREDUCE-4574).
