我尝试在Flink1.4上提交一个作业，得到以下异常。
你知道怎么解决这个问题吗？

多亏了前面回答的“toch”，他给了我解决问题的方向

<exclude>com.esotericsoftware.kryo:kryo</exclude>

已经被排除在我们的 pom.xml 我注意到 kryo-shaded 包括在内
我被加入了pom

<exclude>com.esotericsoftware:kryo-shaded</exclude>

它解决了问题

这是作业jar中的kryo lib和flink中已经加载的kryo lib之间的冲突。
实际上，serializers$specificinstancecollectionserializerforarraylist通过specificinstancecollectionserializer和collectionserializer从com.esotericsoftware.kryo.serializer继承(请参阅flink中的serializers.java和kryo中的collectionserializer.java）。
我们通过从job jar中排除kryo lib来修复它。在gradle build.gradle中，它是通过（如果您使用shadowjar插件）完成的：

configurations {
  runtime.exclude module: 'kryo' , group: 'com.esotericsoftware.kryo'
}

在maven pom.xml中，它是通过（如果您使用shade插件）完成的：

<exclude>com.esotericsoftware.kryo:kryo</exclude>
