> In the configuration of Ranger Presto plugin service, password is not a
> required content. Only when SSL is enabled in Presto, we need to fill in the
> password. When Presto does not enable SSL, if you fill in the password when
> configuring the service, the connection will fail and an exception will be
> thrown.
> {code:java}
> java.sql.SQLException: Authentication using username/password requires SSL to
> be enabled
> {code}
> However, currently in the code, we always put
> {{prop.getProperty(HadoopConfigHolder.RANGER_LOGIN_PASSWORD)}} to
> prestoProperties, if the password is not set,
> {{prop.getProperty(HadoopConfigHolder.RANGER_LOGIN_PASSWORD)}} will be null.
> If we put a null value to {{Properties}}, this will throw NPE. We need to
> check whether we have set the password.
