When creating a Jdbc Catalog, a connection check is performed by default. This is performed on a random FE and BE. If the password is incorrect, the creation of the Catalog will be prohibited. This avoids frequent attempts to use the wrong password on the source library. If the password of the source library is changed midway, it is recommended to stop using or delete the current Catalog first, and then change the password of the Catalog or create the Catalog with the new password after changing the source password. This is to avoid the connection pool constantly trying to connect with the old password to keep the connection alive during the password change process.
Note that the connection test function for creating a Catalog is only on the newer release branch.
