Hi,
CDH-Namenode by default listens in port 8020.
Try
hadoop fs -put /opt/test hdfs://192.168.10.22:8020/user/test
If you get the same message, then open the Namenode WebUI(http://192.168.10.22:50070). In the top, you can see the internal port.Then try to connect using that port.
 
Regards,
Jeba

When you see this, it basically means that you are unable to connected
to the NameNode. It's either not running or running on a different port. please show us your core-site.xml

Thanks & Regards
