Hudson commented on MAPREDUCE-5529: ----------------------------------- SUCCESS: Integrated in Hadoop-trunk-Commit #4486 (See [https://builds.apache.org/job/Hadoop-trunk-Commit/4486/]) MAPREDUCE-5529. Fix compat with hadoop-1 in mapred.TotalOrderPartitioner by re-introducing (get,set)PartitionFile which takes in JobConf. Contributed by Robert Kanter. (acmurthy: http://svn.apache.org/viewcvs.cgi/?root=Apache-SVN&view=rev&rev=1527048) * /hadoop/common/trunk/hadoop-mapreduce-project/CHANGES.txt * /hadoop/common/trunk/hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-core/src/main/java/org/apache/hadoop/mapred/lib/TotalOrderPartitioner.java > Binary incompatibilities in mapred.lib.TotalOrderPartitioner between branch-1 > and branch-2 > ------------------------------------------------------------------------------------------ > > 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.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). -- This message is automatically generated by JIRA.
