      Description

      https://issues.apache.org/jira/browse/MAPREDUCE-2669 introduced 3 new MapReduce examples, but they were never added to the ExamplesDriver.

      This JIRA proposes to add them to the ExamplesDriver. I have ran them myself and can confirm the examples still work as intended.

      As a workaround for now, people can still run them by:
      bin/hadoop org.apache.hadoop.examples.WordMean <input file/dir path> <output dir path>
      bin/hadoop org.apache.hadoop.examples.WordMedian <input file/dir path> <output dir path>
      bin/hadoop org.apache.hadoop.examples.WordStandardDeviation <input file/dir path> <output dir path>

      Post-patch, people will be able to run them by:
      bin/hadoop jar /HADOOP_PATH/share/lib/mapreduce-examples.jar <wordmean|wordmedian|wordstandarddeviation> <input file/dir path> <output dir path>

      Just like they do for running the wordcount example.
