我在flink作业部署中观察到一个非常奇怪的行为。
当我在日食中运行Job时。它运行该工作没有任何问题。
当我在Flink群集中运行相同的作业时，它将失败。我正在使用以下命令来运行作业。
./ flink运行--class FlinkKafkaExample flink-streaming-confluent-1.0-SNAPSHOT-all.jar --inputTopic1 sample-data-topic1 --inputTopic2 sample-data-topic2 --env example.properties
我收到以下错误。

当我检查Jar所需的依赖项时，它在类路径中可用。我什至尝试在flink 1.5.0的lib文件夹中添加相同的jar
其寻找的依赖关系如下所示：
<!-- https://mvnrepository.com/artifact/org.apache.flink/flink-avro -->
<dependency>
<groupId>org.apache.flink</groupId>
<artifactId>flink-avro</artifactId>
<version>1.5.0</version>
</dependency>
