Arun C Murthy reassigned HADOOP-1981:

>                 Key: HADOOP-1981
>                 URL: https://issues.apache.org/jira/browse/HADOOP-1981
>             Project: Hadoop
>          Issue Type: Task
>          Components: mapred

> 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.)
