    Description

      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.
