My application that includes maprfs-0.1.jar is now missing dependencies and fails to link.

As of version 2.1.2 of the MapR distribution, the contents of maprfs-0.1.jar are separated into two parts: maprfs-<version>.jar and maprfs-jni-<version>.jar. The <version> refers to the version of the MapR distribution. For example, if you have an existing application written for maprfs-0.1.jar and you update it to load maprfs-2.1.2.jar, you must also include maprfs-jni-2.1.2.jar. This change was made to enable loading on distributed class-loader environments that use the maprfs libraries to access MapR-FS from multiple contexts.

These JAR files are installed in the /opt/mapr/hadoop/hadoop<version>/lib/ directory, or can be accessed via the Maven Central Repository.
