Example 15 with UnionTypeInfo

use of org.apache.hadoop.hive.serde2.typeinfo.UnionTypeInfo in project hive by apache.

the class TestTypeInfoToSchema method createAvroUnionSchemaWithNull.

@Test
public void createAvroUnionSchemaWithNull() {
    UnionTypeInfo unionTypeInfo = new UnionTypeInfo();
    unionTypeInfo.setAllUnionObjectTypeInfos(Arrays.asList(INT, FLOAT, STRING, VOID));
    final String specificSchema = Schema.createUnion(Arrays.asList(Schema.create(Schema.Type.NULL), Schema.create(Schema.Type.INT), Schema.create(Schema.Type.FLOAT), Schema.create(Schema.Type.STRING))).toString();
    String expectedSchema = genSchemaWithoutNull(specificSchema);
    Assert.assertEquals("Test for union's avro schema failed", expectedSchema, getAvroSchemaString(unionTypeInfo));
