Q:

"mysql 8.0" local infile fails I tried and display the settings. Could it be permission issues?

The following is my session I have the data located in the dir with owner/group of mysql
    mysql -u root -p
    Enter password:

A:

If you're using the LOCAL option with LOAD DATA INFILE, then the secure_file_priv isn't used for the location of the file you load. The file is loaded by the client, so the path you use is not on the server, it's on the client. If you give a relative path, it's relative to the current working directory when you started the client.
However, both the server and the client must enable the --local-infile option.
You've set the option in the server, but you also need to set it in the client like this:
mysql --local-infile -u root -p

I think the error message you got is pretty unhelpful. I logged a bug about it:
Bug #94396 Error message too broad: The used command is not allowed with this MySQL version
Please vote up that bug report if you agree!
