Zhijie Shen created MAPREDUCE-5159:
--------------------------------------

             Summary: Aggregatewordcount and aggregatewordhist in hadoop-1 examples are not binary compatible with hadoop-2 mapred.lib.aggregate
                 Key: MAPREDUCE-5159
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5159
             Project: Hadoop Map/Reduce
          Issue Type: Bug
            Reporter: Zhijie Shen
            Assignee: Zhijie Shen


Both examples in hadoop-1 use org.apache.hadoop.mapred.lib.aggregate.ValueAggregatorJob.createValueAggregatorJob(String args[], Class<?> caller), which no longer exists after upgrading to hadoop-2. Therefore, they cannot not find the accordant function with their function signature in the binary.
