Example 1 with PrimitiveObjectInspectorFactory

use of org.apache.hadoop.hive.serde2.objectinspector.primitive.PrimitiveObjectInspectorFactory in project hive by apache.

the class TestDruidSerDe method serializeObject.

private static void serializeObject(Properties properties, DruidSerDe serDe, Object[] rowObject, DruidWritable druidWritable) throws SerDeException {
    // Build OI with timestamp granularity column
    final List<String> columnNames = new ArrayList<>(Utilities.getColumnNames(properties));
    columnNames.add(Constants.DRUID_TIMESTAMP_GRANULARITY_COL_NAME);
    final List<PrimitiveTypeInfo> columnTypes = Utilities.getColumnTypes(properties).stream().map(TypeInfoFactory::getPrimitiveTypeInfo).collect(Collectors.toList());
    columnTypes.add(TypeInfoFactory.getPrimitiveTypeInfo("timestamp"));
    List<ObjectInspector> inspectors = columnTypes.stream().map(PrimitiveObjectInspectorFactory::getPrimitiveWritableObjectInspector).collect(Collectors.toList());
    ObjectInspector inspector = ObjectInspectorFactory.getStandardStructObjectInspector(columnNames, inspectors);
    // Serialize
    DruidWritable writable = (DruidWritable) serDe.serialize(rowObject, inspector);
    // Check result
    assertEquals(druidWritable.getValue().size(), writable.getValue().size());
    for (Entry<String, Object> e : druidWritable.getValue().entrySet()) {
        assertEquals(e.getValue(), writable.getValue().get(e.getKey()));
    }
