示例1: getStructFieldData
import org.apache.hadoop.io.ArrayWritable; //導入方法依賴的package包/類
@Override
public Object getStructFieldData(final Object data, final StructField fieldRef) {
if (data == null) {
return null;
}
if (data instanceof ArrayWritable) {
final ArrayWritable arr = (ArrayWritable) data;
return arr.get()[((StructFieldImpl) fieldRef).getIndex()];
}
//since setStructFieldData and create return a list, getStructFieldData should be able to
//handle list data. This is required when table serde is ParquetHiveSerDe and partition serde
//is something else.
if (data instanceof List) {
return ((List) data).get(((StructFieldImpl) fieldRef).getIndex());
}
throw new UnsupportedOperationException("Cannot inspect " + data.getClass().getCanonicalName());
}
示例2: writeArray
import org.apache.hadoop.io.ArrayWritable; //導入方法依賴的package包/類
public void writeArray(ArrayWritable aw) throws IOException {
Writable[] writables = aw.get();
out.writeVectorHeader(writables.length);
for (Writable writable : writables) {

}
}
示例3: getStructFieldsDataAsList
import org.apache.hadoop.io.ArrayWritable; //導入方法依賴的package包/類
