 Description   

Our CMAPI service.template has the "root" user assigned. When changing that to another user like "mysql", CMAPI appears to start up correctly however communications between nodes does not work. Nothing but timeouts.

All folders involved are owned by mysql, all nodes in the cluster have the same config.

As per toddstoffel, the root cause is the same as for MCOL-4012, part 1 (permissions to access directories). It will be tracked and fixed there, by jrojas
