Generally if your goal is to secure a MapR cluster you should start by enabling MapR security as well as security for the ecosystem components. This is by far the most important step. After that I would focus on hardening the operating system and network. There are numerous papers on general purpose operating system and network security. If you hit a an issue hardening the operating system or network that appears to impact MapR's operation, let us know.
I'd also create specific admin users rather than sharing the default 'mapr' user as that user is very powerful.
After the above, you will have covered the most important steps to securing a cluster. I'd then turn my attention to areas such as NFSv3 security (MapR optionally exports MapR-FS via NFS v3) as well as setting authorization appropriately throughout the system based upon your requirements.
