Subject [jira] [Commented] (CRUNCH-162) Add utility function for merging output by identity reduce
Date Wed, 06 Feb 2013 12:53:12 GMT


Dave Beech commented on CRUNCH-162:

OK, thanks. Leaving the current sort impl alone makes things easier. Yeah - I'm not sure about
the naming either. I originally created a class PCollections to sit along side PTables in
lib, and called the method forcePartitions (don't particularly like the name, best I could
think of...).
