-------------------------------
Summary: The root cause of a failed job was hidden in certain cases
Key: FLINK-24962
URL: https://issues.apache.org/jira/browse/FLINK-24962
Project: Flink
Issue Type: Improvement
Components: API / Python
Affects Versions: 1.14.0
Reporter: Dian Fu
Fix For: 1.14.1
For the following job:
{code}
from pyflink.common.typeinfo import Types
from pyflink.datastream import StreamExecutionEnvironment, DataStream
from pyflink.table import StreamTableEnvironment
def state_access_demo():
env = StreamExecutionEnvironment.get_execution_environment()
t_env = StreamTableEnvironment.create(stream_execution_environment=env)
sql = """CREATE TABLE kafka_source (
id int,
name string
) WITH (
'connector' = 'kafka',
'topic' = 'test',
'properties.bootstrap.servers' = '***',
'properties.group.id' = '***',
'scan.startup.mode' = 'latest-offset',
'format' = 'json',
'json.fail-on-missing-field' = 'false',
'json.ignore-parse-errors' = 'true'
)"""
t_env.execute_sql(sql)
table = t_env.from_path("kafka_source")
ds: DataStream = t_env.to_append_stream(table,
type_info=Types.ROW([Types.INT(), Types.STRING()]))
ds.map(lambda a: print(a))
env.execute('state_access_demo')
if __name__ == '__main__':
state_access_demo()
{code}
This job failed with the following exception which doesn't contain any useful
information (the root cause is that it should return a value in the map
function):
{code}
