All the basic Hadoop services should be running when you start the Cloudera VM. Port 8020 is for the hadoop-hdfs-namenode service. These services must have failed and just needs to be restarted.

To check the status of a service:

service <service-name> status

To restart a service:

service <service-name> restart

To restart, hadoop-hdfs-namenode service

service hadoop-hdfs-namenode restart

if you get an Error - "root user required", when restarting the service, run with sudo as shwon below:

sudo service hadoop-hdfs-namenode restart

if hadoop-hdfs-datanode service is also not running,

service hadoop-hdfs-namenode restart

Alternatively, You can also start/stop/restart the service by login in to Cloudera Manager from Firefox in Cloudera VM.
