Accessing MapR-FS in Java Applications

As a high-performance filesystem, portions of the MapR-FS file client are based on a native maprfs library. When developing an application, specifying dependence on the JAR file that includes the maprfs library allows you to build applications without having to manage platform-specific dependencies.

The following sections describe how to access MapR-FS in a Java program, and include sample code:
