Example 41 with HiveVarcharWritable

use of org.apache.hadoop.hive.serde2.io.HiveVarcharWritable in project hive by apache.

the class TestGenericUDFOPPlus method testVarcharPlusInt.

@Test
public void testVarcharPlusInt() throws HiveException {
    GenericUDFOPPlus udf = new GenericUDFOPPlus();
    // Short
    HiveVarcharWritable left = new HiveVarcharWritable();
    left.set("123");
    IntWritable right = new IntWritable(456);
    ObjectInspector[] inputOIs = { PrimitiveObjectInspectorFactory.writableHiveVarcharObjectInspector, PrimitiveObjectInspectorFactory.writableIntObjectInspector };
    DeferredObject[] args = { new DeferredJavaObject(left), new DeferredJavaObject(right) };
    PrimitiveObjectInspector oi = (PrimitiveObjectInspector) udf.initialize(inputOIs);
    Assert.assertEquals(oi.getTypeInfo(), TypeInfoFactory.doubleTypeInfo);
