Re:flink1.11.1任务重启 偶现org.apache.kafka.common.KafkaException: Failed to construct kafka consumer异常
HI: 偶现的 ,但是最近几次出现的概率还是比较大的, 之前怀疑classload , 我的jar包做了分离, 不会把任何包打进去, 所以包能确保每次启动都是一样,很奇怪这种情况 在 2020年11月19日 17:14,hailongwang<18868816...@163.com> 写道: Hi, 这个如果是偶尔出现的,应该是跟 ClassLoad 加载有关。 如果 `org.apache.kafka.common.serialization.ByteArrayDeserializer` 被 child classload 加载了, 而 `org.apache.kafka.common.serialization.Deserializer` 被 parent classload 加载了,那么会有问题。 你的 jar 包里面打了 kakfa-connector 的包了吗,如果集群上有,可以provided 看下。 希望对你有帮助。 Best, Hailong Wang 在 2020-11-19 14:33:25,"m13162790856" 写道: >具体日主信息如下: > > > org.apache.kafka.common.KafkaException: Failed to construct kafka consumer >at org.apache.kafka.clients.consumer.KafkaConsumer.(KafkaConsumer.java:789) at org.apache.kafka.clients.consumer.KafkaConsumer.(KafkaConsumer.java:643) at org.apache.kafka.clients.consumer.KafkaConsumer.(KafkaConsumer.java:623) at org.apache.flink.streaming.connectors.kafka.internal.KafkaPartitionDiscoverer.initializeConnections(KafkaPartitionDiscoverer.java:58) at org.apache.flink.streaming.connectors.kafka.internals.AbstractPartitionDiscoverer.open(AbstractPartitionDiscoverer.java:94) at org.apache.flink.streaming.connectors.kafka.FlinkKafkaConsumerBase.open(FlinkKafkaConsumerBase.java:550) at org.apache.flink.api.common.functions.util.FunctionUtils.openFunction(FunctionUtils.java:36) at org.apache.flink.streaming.api.operators.AbstractUdfStreamOperator.open(AbstractUdfStreamOperator.java:102) at org.apache.flink.streaming.runtime.tasks.OperatorChain.initializeStateAndOpenOperators(OperatorChain.java:291) at org.apache.flink.streaming.runtime.tasks.StreamTask.lambda$beforeInvoke$0(StreamTask.java:479) at org.apache.flink.streaming.runtime.tasks.StreamTaskActionExecutor$SynchronizedStreamTaskActionExecutor.runThrowing(StreamTaskActionExecutor.java:92) at org.apache.flink.streaming.runtime.tasks.StreamTask.beforeInvoke(StreamTask.java:475) at org.apache.flink.streaming.runtime.tasks.StreamTask.invoke(StreamTask.java:528) at org.apache.flink.runtime.taskmanager.Task.doRun(Task.java:721) at org.apache.flink.runtime.taskmanager.Task.run(Task.java:546) at java.lang.Thread.run(Thread.java:745) Caused by: org.apache.kafka.common.KafkaException: org.apache.kafka.common.serialization.ByteArrayDeserializer is not an instance of org.apache.kafka.common.serialization.Deserializer at org.apache.kafka.common.config.AbstractConfig.getConfiguredInstance(AbstractConfig.java:263) at org.apache.kafka.clients.consumer.KafkaConsumer.(KafkaConsumer.java:688) ... 15 more 2020-11-19 15:17:32,0 > > >有哪位同学遇见过
