无法从 Data Fusion 连接云 SQL mySql 实例。 异常“无法创建套接字工厂 'com.google.cloud.sql.mysql.SocketFactory”

Question

Facing exception "Could not create socket factory 'com.google.cloud.sql.mysql.SocketFactory' due to underlying exception." when trying to connect with mysql instance in google cloud data fusion.

• created cloud data fusion instance
• From Wrangler-->Add connection --> Added the jar build(created from pom.xml given below) as a driver
• In Add connection used the connection string as "dbc:mysql://google/mysql?cloudSqlInstance=socketFactory=com.google.cloud.sql.mysql.SocketFactory&useSSL=false"
• While Testing the connection, it throws error, "Could not create socket factory 'com.google.cloud.sql.mysql.SocketFactory' due to underlying exception."

This is my pom.xml and I build the fat jar using mvn package.

Answer 1

Use MySQL instead:

1. From the Add Connection> Database Search for MySQL
2. Download the MySQL Driver from dev.mysql.com . Unzip.
3. On the hub again this time click Deploy Upload mysql-connector-java-5.x.xx-bin.jar
4. Go back to Add Connection> Database, you should see green tick against MySQL driver
5. Click on MySQL driver and setup the connection parameter.

Make sure you have added the relevant network in the Cloud SQL screen to allow Datafusion instance to make connection to Cloud SQL. If Datafusion is running in the same project then you dont need to do anything else.
