Subject [jira] [Created] (MAPREDUCE-5157) Sort in hadoop-1 examples is not binary compatible with hadoop-2 mapred.lib
Date Wed, 17 Apr 2013 16:45:15 GMT
Zhijie Shen created MAPREDUCE-5157:
--------------------------------------

             Summary: Sort in hadoop-1 examples is not binary compatible with hadoop-2 mapred.lib
                 Key: MAPREDUCE-5157
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5157
             Project: Hadoop Map/Reduce
          Issue Type: Bug
            Reporter: Zhijie Shen
            Assignee: Zhijie Shen


In SORT example, org.apache.hadoop.mapred.lib.InputSampler.Sampler is used in hadoop-1. However,
after upgrading to hadoop-2, org.apache.hadoop.mapred.lib.InputSampler is modified to extend
org.apache.hadoop.mapreduce.lib.partition.InputSampler, and the inner class, Sampler, has
been moved to the superclass. Therefore, hadoop-1 SORT can not find Sampler when it runs with
hadoop-2 framework.
