>             Project: Hadoop Map/Reduce
>          Issue Type: Bug
>          Components: mrv1, mrv2
>    Affects Versions: 2.1.1-beta
>            Reporter: Robert Kanter

> {{mapred.lib.TotalOrderPartitioner}} in branch-1 has these two methods:
> {code:java}
> public static String getPartitionFile(JobConf job)
> public static void setPartitionFile(JobConf job, Path p)
> {code}
> In branch-2, {{mapred.lib.TotalOrderPartitioner}} is now a subclass of {{mapred.lib.TotalOrderPartitioner}}, from which it inherits the similar methods:
> {code:java}
> public static String getPartitionFile(Configuration conf)
> public static void setPartitionFile(Configuration conf, Path p)
> {code}
> This means that any code that does either of the following:
> {code:java}
> TotalOrderPartitioner.setPartitionFile(new JobConf(), new Path("/"));
> String str = TotalOrderPartitioner.getPartitionFile(new JobConf());
> {code}
> will not be binary compatible (that is, if compiled against branch-1, it will throw a {{NoSuchMethodError}} if run against branch-2).
