回复: flink作业提交到集群执行异常

你好,请问你这个flink作业的pom文件能发一下吗?我猜测你是直接参考官方quickstart修改的.如果是的话,需要激活额外的profile: 
add-dependencies-for-IDEA,并把flink-connector-kafka-0.?_2.11依赖的<scope>provided</scope>标签删掉,或参考profile添加flink-connector-kafka-0.?_2.11的<scope>compile</scope>.这样才会把依赖打包进jar包中.

主题: flink作业提交到集群执行异常

Hi，
现在遇到个问题：Flink消费kafka作业在IDEA上编译执行正常，但是打包后发布到集群上运行报错，已将对应的jar包放到flink的lib路径下了，提交作业无报错！
 请大神帮忙分析一下原因，谢谢！！！

环境如下：
Flink：1.7.2
Kafka：1.1.0
Scala：2.11.8

报错信息如下：
org.apache.flink.streaming.runtime.tasks.StreamTaskException: Cannot load user 
class: org.apache.flink.streaming.connectors.kafka.FlinkKafkaConsumer
ClassLoader info: URL ClassLoader:
