Port:9001

DFS Master

Use M/R Master host: On the front hook. (Because our NameNode and jobtracker are on a machine.) )

Port:9000

User name:Hadoop(the default is the Win system administrator name, because we changed it before, so this becomes Hadoop . )

Then switch to the advanced parameters Options panel, which is configured in detail here, remembering the need to configure with Hadoop (/usr/local/hadoop /etc/hadoop in the configuration file ) , if hadoop.tmp.diris configured, it is necessary to modify it.
