MapR FUSE-Based POSIX Client
The MapR FUSE-based POSIX Client allows app servers, web servers, and other client nodes and apps to read and write data directly and securely to a MapR cluster like a Linux filesystem.
The FUSE-based MapR POSIX client runs as a userspace process to connect to one or more MapR
clusters. The necessary FUSE (Filesystem in Userspace) library (libfuse
) is
bundled with POSIX client package. With the installation of the POSIX client package, the MapR
POSIX client performs operations like read and write on the filesystem exposed by FUSE. The
following diagram illustrates how the MapR FUSE-based POSIX client works.
The table below summarizes the differences between the POSIX loopback NFS client and the FUSE-based POSIX Basic and Platinum clients:
