   @Slivery1 
   In my memory, the hadoop or yarn jar command should be
   ```
   hadoop jar <jar> [mainClass] [GENERIC_OPTIONS] args...
   yarn jar <jar> [mainClass] [GENERIC_OPTIONS] args...
   ```
   Refs:
   - [hadoop commands](http://hadoop.apache.org/docs/r2.8.5/hadoop-project-dist/hadoop-common/CommandsManual.html)
   - [mapreduce tutorial](http://hadoop.apache.org/docs/r2.8.5/hadoop-mapreduce-client/hadoop-mapreduce-client-core/MapReduceTutorial.html)
   ```
   hadoop [--config confdir] [--loglevel loglevel] [COMMAND] [GENERIC_OPTIONS] [COMMAND_OPTIONS]
   hadoop jar <jar> [mainClass] args...
   ```
   Examples:
   ```
   bin/hadoop jar hadoop-mapreduce-examples-<ver>.jar wordcount -files cachefile.txt -libjars mylib.jar -archives myarchive.zip input output
   ```
   
   Let me check it and fix it if there is a problem.
