Affects Version/s: 7.1.10 DXP FP11
Component/s: Fault Tolerance > Clustering Framework
Liferay 7.1 does not currently have these changes backported: https://issues.liferay.com/browse/LPS-92491 which allow Liferay to use the latest Mysql v8.0.16 JDBC driver in the JDBC_PING context
When trying to setup a LIferay 7.1 cluster with the latest Mysql driver, no error messages are generated in the logs but the cluster is not actually formed. Instead each node functions as its own master.
Ideally there should be a log message indicating that the JDBC_PING connection failed.
Steps to reproduce:
1. Set up a liferay cluster with 7.1 but using the latest mysql driver (e.g. v.8.0.16)
2. Configure the cluster to use JDBC_PING e.g.:
3. Start the cluster.
An error message appears in the logs explaining that it was not possible to establish a connection to the database
No error is displayed and the cluster is not formed.
