Dear， I write a MR based on HBase. When I run "java jar mr.jar" I can not see any jobs on hadoop web UI. And when I run 'hadoop jar mr.jar" I can get my jobs on hadoop web UI. But the speed is very very slow. And I can not see the tasks on the datanode web console.
How should I use ? java jar mr.jar or hadoop jar mr.jar thanks Best Regards
