Zili Chen updated FLINK-34962: ------------------------------ Affects Version/s: (was: pulsar-4.1.1) > flink-connector-pulsa starts failed due to incorrect use of Pulsar API: > LookupService. getPartitionedTopicMetadata > ------------------------------------------------------------------------------------------------------------------ > > Key: FLINK-34962 > URL: https://issues.apache.org/jira/browse/FLINK-34962 > Project: Flink > Issue Type: Bug > Components: Connectors / Pulsar > Environment: * flink 1.17 > * pulsar client 3.0.0 > * org.apache.flink:flink-connector-pulsar:4.1.0-1.17 (connector) > Reporter: Yubiao Feng > Priority: Major > Labels: easyfix, pull-request-available > Fix For: pulsar-4.2.0 > > > - The unnecessary codes calls > `pulsarClient.getLookup().getPartitionedTopicMetadata()` to create the > partitioned topic metadata(in fact, this behavior of is not correct) > - Why it is unnecessary: the [following > code]([https://github.com/apache/flink-connector-pulsar/blob/main/flink-connector-pulsar/src/main/java/org/apache/flink/connector/pulsar/sink/writer/topic/ProducerRegister.java#L245]) > that is creating a producer will also trigger partitioned topic metadata to > create. > - The method `pulsarClient.getLookup().getPartitionedTopicMetadata()` will > not retry if the connection is closed so that users will get an error. The > following code creates a producer that will retry if the connection is > closed, reducing the probability of an error occurring. -- This message was sent by Atlassian Jira (v8.20.10#820010)
