- All Known Implementing Classes:
- RDFInputFormat, TitanCassandraOutputFormat, TitanHBaseOutputFormat, TitanOutputFormat
public interface MapReduceFormat
If an Input- or OutputFormat requires some pre-post processing, then a MapReduceFormat can be implemented.
For InputFormats, the MapReduce jobs are prepended to the job pipeline and the final job must yield a HadoopVertex stream.
For OutputFormats, the MapReduce jobs are appended to the job pipeline and the first job must consume a HadoopVertex stream.
