----------------------------------
Summary: Integration with DataStream and DataSet API report error
Key: FLINK-18724
URL:
https://issues.apache.org/jira/browse/FLINK-18724 Project: Flink
Issue Type: Bug
Components: API / Core, Connectors / Kafka, Table SQL / API
Affects Versions: 1.11.1
Reporter: liang ding
I want to create a table from a DataStream(kafka) : there is two reason I need to use DataStream:
# I need decode msg to columns by custom format, in sql mode I don't known how to do it.
# I have realize DeserializationSchema or FlatMapFunction both. when use datastream I can do many things before it become a suitable table, that is my prefer way in any other apply.
so I do it like that:
{code:java}
StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();
EnvironmentSettings tSet= EnvironmentSettings.newInstance().useOldPlanner().inStreamingMode().build();
StreamTableEnvironment tEnv=StreamTableEnvironment.create(env,tSet);
DataStream<MyRow> stream = env
.addSource(new FlinkKafkaConsumer<>("test-log", new SimpleStringSchema(), properties))
.flatMap(new LogParser());
//stream.printToErr();
tEnv.fromDataStream(stream).select("userId,city").execute().print();
tEnv.execute("test-sql");
//env.execute("test");
{code}
then I got message:
{noformat}
[Kafka Fetcher for Source: Custom Source -> Flat Map ->* -> select: (userId,city) -> to: Row (3/3)] INFO org.apache.kafka.clients.FetchSessionHandler - [Consumer clientId=consumer-flink-3-5, groupId=flink-3] Node 0 sent an invalid full fetch response with extra=(test-log-0, response=(
[Kafka Fetcher for Source: Custom Source -> Flat Map ->* -> select: (userId,city) -> to: Row (3/3)] INFO org.apache.kafka.clients.FetchSessionHandler - [Consumer clientId=consumer-flink-3-5, groupId=flink-3] Node 0 sent an invalid full fetch response with extra=(test-log-1, response=({noformat}
it seen like both StreamExecutionEnvironment and StreamTableEnvironment start the fetcher and make no one successed.
and there is no guide Integration which made me confused： should I do env.execute or
tableEnv.execute or both(it's seen not) ? and the blink planner way
