看起来很简单的问题， 但是总报错。。
代码：
source_ddl = """
CREATE TABLE test_source_table_1(
a VARCHAR,
b INT
) WITH (
'connector' = 'kafka',
'topic' = 'test1',
'properties.bootstrap.servers' = 'localhost:9092',
'scan.startup.mode' = 'latest-offset',
'format' = 'json'
)
"""
pyflink版本：
apache-flink 1.12.2
导入的jar包：flink-connector-kafka_2.11-1.12.2.jar
python执行报错信息：
py4j.protocol.Py4JJavaError: An error occurred while calling o4.sqlQuery.
