| /** |
| * Reads RDF data from one or more file(s) and inserts statements into Rya. |

| * Uses {@link org.apache.rya.accumulo.mr.RdfFileInputFormat} to read data. |
| * <p> |
| * Takes one argument: the file or directory to read (from HDFS). |
| * <p> |
| * Expects configuration: |
| * <p> |
| * - RDF format, named by parameter "rdf.format"; see {@link RDFFormat}. |
| * Defaults to rdf/xml. If using multiple files, all must be the same format. |
| * <p> |
| * - Accumulo and Rya configuration parameters as named in {@link MRUtils} |
| * (username, password, instance name, zookeepers, and Rya prefix) |
| * <p> |
| * - Indexing configuration parameters as named in |
| * {@link org.apache.rya.indexing.accumulo.ConfigUtils} (enable or disable freetext, |
| * geo, temporal, and entity indexing, and specify predicates for each |
| * indexer). If not given, no secondary indexing is done. |
