      Description

      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.
