      When I try to use hadoop mapreduce framework with Turkish locale that set default mapreduce.map.java.opts and mapreduce.reduce.java.opts to -Duser.language=tr. It throws exception.

      After Long research, i found a little bug in org.apache.hadoop.security.SaslPropertiesResolver line 68. default setting of hadoop.rpc.protection is authentication. When i make locale Turkish authentication parameter with toUpperCase become AUTHENTÄ°CATÄ°ON. Please attention to dotted big i. This is a Turkish letter. It is very similar big i, it just have addition dot.

      IMHO who-one use upper or lowercase method for settings, it should use Locale.ENGLISH. I created a patch file. But I could not test it. I can not find which tests should i run. If you show me, I will be glad.

      BTW I think, Hadoop Tests should be run different locale.

      p.s. Exception is generated by a Hive query. It can be generated by any map reduce job.
