Glue Job Communications link failure, MariaDB

2

I was running glue job to process data from MariaDB inside VPC. Recently my glue job get "com.mysql.cj.jdbc.exceptions.CommunicationsException: Communications link failure" although it was running fine before. My preliminary research is this due to it cant connect to DB, but Glue Connection and Glue Crawler works fine, only when using job that it get the above error.

My theory is this issue is due to MariaDB auto update (minor versions). I'm stuck and couldn't find a solution. Any people using MariaDB experience the same?

  • Have you solved the issue?

    I'm facing the same issue. RDS and Redshift connections are successful. Crawlers can crawl data. Glue job fails with Communications link failure error.

  • Did you manage to solve the problem? If it doesn't work, I'll have to migrate from MariaDB to MySQL.
