I am getting core-site.xml (Permission denied) below when using Oozie-Spark workflow.
I have access to this directory /opt/data/yarn/local/usercache/oozie/appcache
drwxrwxrwx 2 yarn hadoop 10 Jul 20 11:30 appcache
Could anyone please help me why I am getting the Permission denied?
I really appreciated.

As the error itself says, the oozie user is not able to access the file most probably.
So, check the permission on the entire path to the file, not just the very last folder in the file path.
