@Test
public void testNoIndexExpression() throws Exception {
IndexExpression exp = new NoIndexExpression();
Scan scan = new Scan();
scan.setAttribute(Constants.INDEX_EXPRESSION, IndexUtils.toBytes(exp));
byte[] value1 = Bytes.toBytes("asdf");
scan.setFilter(new SingleColumnValueFilter(FAMILY1, QUALIFIER1, CompareOp.EQUAL, value1));
List<IndexSpecification> indices = new ArrayList<IndexSpecification>();
IndexSpecification is1 = new IndexSpecification("idx1");
HColumnDescriptor colDesc = new HColumnDescriptor(FAMILY1);
is1.addIndexColumn(colDesc, COL1, ValueType.String, 15);
