ST_AsShape for Hive

I found the following untracked file, never committed to git - probably did not pass testing:

package com.esri.hadoop.hive;

import java.nio.ByteBuffer;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.apache.hadoop.hive.ql.exec.UDFArgumentException;
import org.apache.hadoop.io.BytesWritable;

import com.esri.core.geometry.SpatialReference;
import com.esri.core.geometry.ogc.OGCGeometry;

public class ST_GeomFromShape extends ST_Geometry {

    static final Log LOG = LogFactory.getLog(ST_GeomFromShape.class.getName());

    public BytesWritable evaluate(BytesWritable shape) throws UDFArgumentException {
        return evaluate(shape, 0);
    }

    public BytesWritable evaluate(BytesWritable shape, int wkid) throws UDFArgumentException {

        //String wkt = shape.toString();
        LOG.error("geom-from-shape");  /// debug/todo
        try {
            SpatialReference spatialReference = null;
            if (wkid != GeometryUtils.WKID_UNKNOWN) {
                spatialReference = SpatialReference.create(wkid);
            }
            // byte [] byteArr = shape.getBytes();
            // ByteBuffer byteBuf = ByteBuffer.allocate(byteArr.length);
            // byteBuf.put(byteArr);
            // TODO: little-endian order: .order(ByteOrder.LITTLE_ENDIAN)
            OGCGeometry ogcObj = OGCGeometry.fromEsriShape(ByteBuffer.wrap(shape.getBytes()));
            ogcObj.setSpatialReference(spatialReference);
            return GeometryUtils.geometryToEsriShapeBytesWritable(ogcObj);
        } catch (Exception e) {
            LogUtils.Log_ExceptionThrown(LOG, "geom-from-shape", e);  //todo
            return null;
        }
    }

}

Need to add to the documentation on wiki
