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
