Example 36 with DoubleWritable

use of org.apache.hadoop.io.DoubleWritable in project hive by apache.

the class TestETypeConverter method testGetFloatConverterForDouble.

@Test
public void testGetFloatConverterForDouble() throws Exception {
    MyConverterParent converterParent = new MyConverterParent();
    PrimitiveType primitiveType = Types.optional(PrimitiveTypeName.FLOAT).named("value");
    PrimitiveConverter converter = ETypeConverter.getNewConverter(primitiveType, 1, converterParent, createHiveTypeInfo("double"));
    ((PrimitiveConverter) converter).addFloat(3276f);
    Writable writable = converterParent.getValue();
    DoubleWritable doubleWritable = (DoubleWritable) writable;
    assertEquals(3276d, doubleWritable.get(), 0);
}
