@InterfaceAudience.LimitedPrivate(value="Coprocesssor")
 @InterfaceStability.Evolving
public class Export
extends ExportProtos.ExportService
implements RegionCoprocessor

Export an HBase table. Writes content to sequence files up in HDFS. Use Import to read it back in again. It is implemented by the endpoint technique.
