> I tried to submit mr example job wordmedian and specify queue by -D option:
> {{bin/hadoop jar ~/hadoop-mapreduce-examples-2.8.2-bc1.4.0.jar wordmedian -Dmapreduce.job.queuename=root.user1 /input /output6}}. This option did not work in wordmedian while it works in other example jobs such Terasort, Wordcount.
> The cause is there is unnecessary {{setConf(new Configuration())}} in {{run()}} method, which would override Configuration with properties by -D options.
