Subject [jira] [Updated] (MAPREDUCE-5529) Binary incompatibilities in mapred.lib.TotalOrderPartitioner between branch-1 and branch-2
Date Tue, 24 Sep 2013 00:19:03 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-5529?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Robert Kanter updated MAPREDUCE-5529:
-------------------------------------

    Description: 
{{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).
