When I execute the hopsworks-installer.sh (2.2)，there is a warning message:
WARNING: Reverse DNS does not work on this host. If you enable ‘TLS’, it will not work.
Reverse Hostname: bogon
Azure installation: please continue, we will try and fix this during the installation.
On-premises: you have to configure your networking to make reverse-DNS work correctly.
What is the Reverse DNS? How do I install or configure it？
