Answer 1

Get rid of trailing whitespaces in mysql.properties file. I had a similar issue while working with Kafka connector (No factory for connector kafka) and realized that trailing whitespaces were causing the problem. After removing the whitespaces in kafka.properties I got it working.

Answer 2

The mysql plugin is definitely part of Presto 336, the version you are using.

I would assume the <presto-install-dir>/plugin/mysql directory got removed somehow on local installation.

Answer 3

You need to add "datasource.driver" to your 'mysql.properties' file.
