ChangWinde commented on issue #4721: Flink pulsar sink NotSerializableException
URL: https://github.com/apache/pulsar/issues/4721#issuecomment-532563252
I run into similar problem.
I follow the
https://github.com/apache/pulsar/blob/master/examples/flink/src/main/java/org/apache/flink/streaming/connectors/pulsar/example/README.md
and I execute the './bin/flink run -c
org.apache.flink.streaming.connectors.pulsar.example.PulsarConsumerSourceWordCount
${PULSAR_HOME}/examples/flink/target/pulsar-flink-examples.jar --service-url
pulsar://localhost:6650 --input-topic test_src --subscription test_sub'
successfully. But when I add the parameter 'output-topic', it will throw
exception.
Exception information followed：
org.apache.pulsar.client.impl.DefaultBatcherBuilder@75d2da2d is not
serializable. The object probably contains or references non serializable
fields.
