单任务多条流的逻辑报错

Hi all:

请问我用flink1.10.2版本，写了1个代码，这个代码本地可以跑起来，但是以任务方式发布到flink中，启动就报错，异常如下, 请问是什么原因？

大致逻辑如下，我有2条流：
1.通过多个kafkasource，得到多个流后union，然后这个union的单流经过2个算子，最后sink到kafka
2.通过单个kafkasource，得到流，经过1个算子，最后sink到kafka
代码如下：
StreamExecutionEnvironment streamExecutionEnvironment = StreamExecutionEnvironment.getExecutionEnvironment();
List<KafkaInfo> kafkaSourceConfiguration = this.kafkaConfiguration.getSource0();
KafkaInfo kafkaSinkConfiguration = this.kafkaConfiguration.getSink();
RecordTransformOperator transformOperator = new RecordTransformOperator(DefRecordTransform.CHAIN_TYPE_TRANSFORM_COMPUTE);
RecordKeySelector keySelector = new RecordKeySelector();
RecordComputeOperator computeOperator = new RecordComputeOperator();
Properties sinkProperties = new Properties();
sinkProperties.setProperty("bootstrap.servers", kafkaSinkConfiguration.getBootstrapServer());
FlinkKafkaProducer011 flinkKafkaProducer
= new FlinkKafkaProducer011(kafkaSinkConfiguration.getTopicName(), new KafkaSerializer(), sinkProperties);

List<SingleOutputStreamOperator<Tuple2<String, String>>> dataStreamList = new ArrayList<>();
for (KafkaInfo kafkaInfo : kafkaSourceConfiguration) {
Properties sourceProperties = new Properties();
sourceProperties.setProperty("bootstrap.servers", kafkaInfo.getBootstrapServer());
sourceProperties.setProperty("group.id", kafkaInfo.getGroupId());
sourceProperties.setProperty("max.poll.records", kafkaInfo.getMaxPollRecord());
sourceProperties.put("max.poll.interval.ms", kafkaInfo.getMaxPollIntervalMs());
String topicName = kafkaInfo.getTopicName();
FlinkKafkaConsumer011<Tuple2<String, String>> flinkKafkaConsumer
= new FlinkKafkaConsumer011(topicName,
new KafkaDeserializer(),
sourceProperties);
SingleOutputStreamOperator<Tuple2<String, String>> singleOutputStreamOperator =
streamExecutionEnvironment.addSource(flinkKafkaConsumer);
dataStreamList.add(singleOutputStreamOperator);
}

DataStream<Tuple2<String, String>> unionDataStream = dataStreamList.get(0);
for(int i = 1; i<dataStreamList.size(); i++) {
unionDataStream = unionDataStream.union(dataStreamList.get(i));
}
unionDataStream.flatMap(transformOperator)
.keyBy(keySelector)
.flatMap(computeOperator)
.addSink(flinkKafkaProducer);

RecordTransformOperator transformOperator1 = new RecordTransformOperator(DefRecordTransform.CHAIN_TYPE_TRANSFORM);
Properties sinkProperties1 = new Properties();
sinkProperties1.setProperty("bootstrap.servers", kafkaSinkConfiguration.getBootstrapServer());
FlinkKafkaProducer011 flinkKafkaProducer1
= new FlinkKafkaProducer011(kafkaSinkConfiguration.getTopicName(), new KafkaSerializer(), sinkProperties1);
KafkaInfo kafkaInfo = this.kafkaConfiguration.getSource1().get(0);
Properties sourceProperties = new Properties();
sourceProperties.setProperty("bootstrap.servers", kafkaInfo.getBootstrapServer());
sourceProperties.setProperty("group.id", kafkaInfo.getGroupId());
sourceProperties.setProperty("max.poll.records", kafkaInfo.getMaxPollRecord());
sourceProperties.put("max.poll.interval.ms", kafkaInfo.getMaxPollIntervalMs());
String topicName = kafkaInfo.getTopicName();
FlinkKafkaConsumer011<Tuple2<String, String>> flinkKafkaConsumer
= new FlinkKafkaConsumer011(topicName,
new KafkaDeserializer(),
sourceProperties);
streamExecutionEnvironment
.addSource(flinkKafkaConsumer)
.flatMap(transformOperator1)
.addSink(flinkKafkaProducer1);
streamExecutionEnvironment.execute();

Hi,
根据报错内容，定位到你的代码在
at
org.apache.flink.util.InstantiationUtil.deserializeObject(InstantiationUtil.java:576)
at
org.apache.flink.util.InstantiationUtil.deserializeObject(InstantiationUtil.java:562)
at
org.apache.flink.util.InstantiationUtil.deserializeObject(InstantiationUtil.java:550)
at
org.apache.flink.util.InstantiationUtil.readObjectFromConfig(InstantiationUtil.java:511)
InstantiationUtil类的处理有问题，应该是反序列化问题。本地测试没问题，是因为本地不涉及到序列化。

Best,
Robin

Re: Re: 单任务多条流的逻辑报错

InstantiationUtil这个类我代码中并未显示调用，具体应该如何定位问题原因，烦请看下能否提供下可行的解决方案
