Hello @Jitendra7337-8043,

You need to use root permissions to edit file under /etc folder.

Syntax:

sudo <Favorite Editor > core-site.xml

Error: Gives error message as “you don’t have permissions to edit the file”.

 cd /etc/hadoop/conf
 nano core-site.xml 

Success: Allows to edit the file.

 cd /etc/hadoop/conf
 sudo nano core-site.xml 

Hope this helps. Do let us know if you any further queries.
