Todd Lipcon commented on MAPREDUCE-1287:
----------------------------------------
- Can you also make this change to the old API HashPartitioner?
src/java/org/apache/hadoop/mapred/lib/HashPartitioner.java
- The "else" on a separate line from the '}' is different style than the usual
Hadoop style. Also a space after 'if' is usual style.
> HashPartitioner calls hashCode() when there is only 1 reducer
