------------------------------------------------
+1. Should have committed this earlier.
> WordMean, WordMedian, WordStandardDeviation missing from ExamplesDriver

> Key: MAPREDUCE-4981
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-4981
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Affects Versions: 3.0.0, 2.0.3-alpha
> Reporter: Plamen Jeliazkov
> Assignee: Plamen Jeliazkov
> Priority: Minor
> Fix For: 3.0.0, 2.0.5-beta
>
> Attachments: MAPREDUCE-4981.patch
>
>
> 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.
