public final class MapRFileSystem extends FileSystem
FileSystem base class for the MapR
file system. The class contains MapR specific code to initialize the
connection to the file system. Apart from that, we code mainly reuses the
existing HDFS wrapper code.FileSystem.FSKey, FileSystem.WriteMode| Constructor and Description |

MapRFileSystem()
Creates a new MapRFileSystem object to access the MapR file system.
