shiv4289 opened a new issue #4283: flink job crashes when serializing auth in pulsar client
URL: https://github.com/apache/pulsar/issues/4283
 
 
   **Describe the bug**
   pulsar flink connector now uses ClientConfigData to instantiate pulsar client. Pulsar client composes Authentication which can not be serialized. In an environment with Auth there is no way to set auth in pulsar client.
   
   **To Reproduce**
   The below code crashes on last line:
   
   >         ClientConfigurationData clientConfig = new ClientConfigurationData();
   >         clientConfig.setServiceUrl(PULSAR_BROKER_URL);
   >         clientConfig.setAuthPluginClassName(AuthenticationToken.class.getName());
   >         clientConfig.setAuthParams(ImmutableMap.of("token", PULSAR_AUTH_TOKEN));
   > 
   >         ConsumerConfigurationData consumerConfig = new ConsumerConfigurationData();
   >         consumerConfig.setSubscriptionInitialPosition(SubscriptionInitialPosition.Earliest);
   >         consumerConfig.setTopicNames(new HashSet<>(Arrays.asList(PULSAR_TOPIC)));
   >         consumerConfig.setSubscriptionName(PULSAR_SUBSCRIPTION_NAME);
   > 
   >         PulsarSourceBuilder pulsarSourceBuilder = PulsarSourceBuilder.builder(new SimpleStringSchema())
   >                 .pulsarAllClientConf(clientConfig)
   >                 .pulsarAllConsumerConf(consumerConfig);
   > 
   >         StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();
   > 
   >         env.setStreamTimeCharacteristic(TimeCharacteristic.ProcessingTime);
   > 
   >         SourceFunction src = pulsarSourceBuilder.build();
   >         DataStream dataStream = env.addSource(src).uid("testStream");
   
   **Expected behavior**
   Provide a way to set Auth for pulsar client from pulsar flink connector
