org.apache.hadoop.hbase.rest.model.RowModel
Representation of a row. A row is a related set of cells, grouped by common row key. RowModels do not appear in results by themselves. They are always encapsulated within CellSetModels.
```
 <complexType name="Row"> <sequence> <element name="key" type="base64Binary"></element> <element name="cell" type="tns:Cell"  maxOccurs="unbounded" minOccurs="1"></element> </sequence> </complexType>
