I have the same problem that I am receiving "No such file or directory" when trying to access a file in DBFS using a cluster in shared access mode. I am using shared access mode because I want to use table access controls.

I ran "GRANT ALL PRIVILEGES ON ANY FILE TO <user>" and "SHOW GRANTS ON ANY FILE" to verify the grant went through, but am still unable to access the file in DBFS. 

@Retired_mod could you advise? Thanks!
