> LazyHBaseRow
> {code}
> private Object uncheckedGetField(int fieldID) {
> if(!fieldsInited[fieldID]) {
> fieldsInited[fieldID] = true;
> byte [] res = result.getValue(colMap.familyNameBytes,
> colMap.qualifierNameBytes);
> if (res == null) {
> return null;
> }
> }
> return fields[fieldID].getObject();
> }
> {code}
> if there is a LazyHBaseRow instance row, the fieldID is 0, we assume this
> field is null, so the first time row.uncheckedGetField(0) will return null,
> but the second time when row.uncheckedGetField(0) will return
> fields[fieldID].getObject(), this is the last cache data.
