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 filesystem from multiple
contexts.
