Examples with FilterLongColGreaterLongScalar org.apache.hadoop.hive.ql.exec.vector.expressions.gen.FilterLongColGreaterLongScalar used on opensource projects

Example 1 with FilterLongColGreaterLongScalar

use of org.apache.hadoop.hive.ql.exec.vector.expressions.gen.FilterLongColGreaterLongScalar in project hive by apache.

the class TestVectorFilterExpressions method testColOpScalarNumericFilterNullAndRepeatingLogic.

@Test
public void testColOpScalarNumericFilterNullAndRepeatingLogic() throws HiveException {
    // No nulls, not repeating
    FilterLongColGreaterLongScalar f = new FilterLongColGreaterLongScalar(0, 1);
    VectorizedRowBatch batch = this.getSimpleLongBatch();
    batch.cols[0].noNulls = true;
    batch.cols[0].isRepeating = false;
    f.evaluate(batch);
    // only last 2 rows qualify
    Assert.assertEquals(2, batch.size);
    // show that their positions are recorded
    Assert.assertTrue(batch.selectedInUse);
    Assert.assertEquals(2, batch.selected[0]);
    Assert.assertEquals(3, batch.selected[1]);
    // make everything qualify and ensure selected is not in use
    // col > -1
    f = new FilterLongColGreaterLongScalar(0, -1);
    batch = getSimpleLongBatch();
    f.evaluate(batch);
    Assert.assertFalse(batch.selectedInUse);
    Assert.assertEquals(4, batch.size);
    // has nulls, not repeating
    batch = getSimpleLongBatch();
    // col > 1
    f = new FilterLongColGreaterLongScalar(0, 1);
    batch.cols[0].noNulls = false;
    batch.cols[0].isRepeating = false;
    batch.cols[0].isNull[3] = true;
    f.evaluate(batch);
    Assert.assertTrue(batch.selectedInUse);
    Assert.assertEquals(1, batch.size);
    Assert.assertEquals(2, batch.selected[0]);
    // no nulls, is repeating
    batch = getSimpleLongBatch();
    // col > -1
    f = new FilterLongColGreaterLongScalar(0, -1);
    batch.cols[0].noNulls = true;
    batch.cols[0].isRepeating = true;
    f.evaluate(batch);
    Assert.assertFalse(batch.selectedInUse);
    // everything qualifies (4 rows, all with value -1)
    Assert.assertEquals(4, batch.size);
    // has nulls, is repeating
    batch = getSimpleLongBatch();
    batch.cols[0].noNulls = false;
    batch.cols[0].isRepeating = true;
    batch.cols[0].isNull[0] = true;
    f.evaluate(batch);
    // all values are null so none qualify
    Assert.assertEquals(0, batch.size);

Example 2 with FilterLongColGreaterLongScalar

use of org.apache.hadoop.hive.ql.exec.vector.expressions.gen.FilterLongColGreaterLongScalar in project hive by apache.

the class TestVectorizationContext method testFilterWithNegativeScalar.

@Test
public void testFilterWithNegativeScalar() throws HiveException {
    ExprNodeColumnDesc col1Expr = new ExprNodeColumnDesc(Integer.class, "col1", "table", false);
    ExprNodeConstantDesc constDesc = new ExprNodeConstantDesc(Integer.valueOf(-10));
    GenericUDFOPGreaterThan udf = new GenericUDFOPGreaterThan();
    ExprNodeGenericFuncDesc exprDesc = new ExprNodeGenericFuncDesc();
    exprDesc.setGenericUDF(udf);
    List<ExprNodeDesc> children1 = new ArrayList<ExprNodeDesc>(2);
    children1.add(col1Expr);
    children1.add(constDesc);
    exprDesc.setChildren(children1);
    List<String> columns = new ArrayList<String>();
    columns.add("col0");
    columns.add("col1");
    columns.add("col2");
    VectorizationContext vc = new VectorizationContext("name", columns);
    VectorExpression ve = vc.getVectorExpression(exprDesc, VectorExpressionDescriptor.Mode.FILTER);
    assertTrue(ve instanceof FilterLongColGreaterLongScalar);
