As of version 2.1.2 of the MapR distribution, the contents of
maprfs-0.1.jar are separated into two parts:
<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.
JAR files are installed in the
/opt/mapr/hadoop/hadoop<version>/lib/ directory, or can be accessed via the Maven Central Repository.
