Installing the mapr-loopbacknfs Package

MapR POSIX clients enable application servers, web servers, and other client nodes and applications to read and write directly and securely to a MapR cluster.

You can install the mapr-loopbacknfs client on any client node, even your laptop, if you have Linux installed. This feature requires a loopbacknfs license, which is limited to a single user.

A client node must have a supported Linux OS distribution and must be outside the MapR cluster, not running mapr-fileserver or other Hadoop services. You cannot install the MapR POSIX client on a Windows or Mac OS X machine.

Attention: MapR does not recommend installing the mapr-loopbacknfs client on a cluster node.

To install mapr-loopbacknfs on your machine, perform the following steps for your version of Linux, as the root user or using sudo. The package is installed to the /usr/local/mapr-loopbacknfs directory.
