Need to document the controls for sorting and grouping into the reduce
----------------------------------------------------------------------
Key: HADOOP-1981
URL: https://issues.apache.org/jira/browse/HADOOP-1981
Project: Hadoop
Issue Type: Task
Components: mapred
Reporter: Owen O'Malley
Assignee: Owen O'Malley
Fix For: 0.15.0
The JavaDoc for the Reducer should document how to control the sort order of
keys and values via the JobConf methods:
{code}
setOutputKeyComparatorClass
setOutputValueGroupingComparator
{code}
Both methods desperately need better names. (I'd vote for
setKeySortingComparator and setKeyGroupingComparator.)
