Unauthorized connection for super-user: root from IP

When trying to upload files to hdfs through ambari console getting the below error

Unauthorized connection for super-user: root from IP

Looks like we have not added the mentioned IP Address properly inside the property: hadoop.proxyuser.root.hosts

If ambari-server daemon is running as root, we need to set up a proxy user for root in core-site by adding and changing properties in HDFS > Configs > Custom core-site:
  1. hadoop.proxyuser.root.groups=*
  2. hadoop.proxyuser.root.hosts=*
Open ambari console

Go to HDFS -> Configs

Click on Custom core-site

Modify the below parameters

Save the configuration

Click ok

Restart the affected components

After successful restart try to upload files now
