> Binary incompatibilities in mapred.lib.TotalOrderPartitioner between branch-1

> ------------------------------------------------------------------------------------------
>
> Key: MAPREDUCE-5529
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-5529
> Project: Hadoop Map/Reduce
> Issue Type: Sub-task
> Components: mrv1, mrv2
> Affects Versions: 2.1.1-beta
> Reporter: Robert Kanter
> Assignee: Robert Kanter
> Priority: Blocker
> Attachments: MAPREDUCE-5529_branch_2.patch, MAPREDUCE-5529.patch,
> MAPREDUCE-5529.patch
>
>
> {{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).
