>
> Since Presto service allows not to set password, when constructing
> {{HadoopConfigHolder}}, we need to check whether {{RANGER_LOGIN_PASSWORD}} is
> set. If it is not set, we need to set it to null in connectionProperties in
> order to make the password in dataSource2HadoopConfigHolder be updated.
> Otherwise, when we set the password in the Presto service, the static
> variable {{dataSource2HadoopConfigHolder}} will store the password. If we
> change the password in the Presto service to empty, if we do not check the
> {{RANGER_LOGIN_PASSWORD}}, the old password stored in
> {{dataSource2HadoopConfigHolder}} will never be updated, causing the presto
> client connection to fail.
