> `PasswordPlaceholderConfigurer` tries to decode potential password values. But if we use a placeholder with default value and not explictly provide password, it'll raise an runtime exception when Kylin server starts up.
> In my case, ${xx.redis.password:} is used as redis password placeholder. Because no password is needed for my redis instance, so xx.redis.password is left out in kylin.properties, and the server fails to start up:
