我们运行 Flink 1.3.0 CEP 作业并依赖 Avro 1.8.1(LogicalType 在 Avro 1.7.7 中不存在)来序列化复杂事件(作为 POJO)。它在 IDE (IntelliJ) 中运行时可以工作,但是当我们打包 jar 文件并将其部署到集群时,我们得到:

java.lang.NoSuchMethodError: org.apache.avro.Schema.setLogicalType(Lorg/apache/avro/LogicalType;)V
at org.apache.avro.LogicalType.addToSchema(LogicalType.java:72)

但是,似乎我们构建的 jar 包含关于构建输出的正确 Avro 包版本(1.8.1)。

mvn clean package -Pbuild-jar
...
[INFO] Including org.apache.avro:avro:jar:1.8.1 in the shaded jar.
...

问题:我们如何确保我们的 Flink 集群使用正确的 Avro 版本(1.8.1)?

<!-- 

    Execute "mvn clean package -Pbuild-jar"
    to build a jar file out of this project!

    How to use the Flink Quickstart pom:

    a) Adding new dependencies:
        You can add dependencies to the list below.
        Please check if the maven-shade-plugin below is filtering out your dependency
        and remove the exclude from there.

    b) Build a jar for running on the cluster:
        There are two options for creating a jar from this project

        b.1) "mvn clean package" -> this will create a fat jar which contains all
                dependencies necessary for running the jar created by this pom in a cluster.
                The "maven-shade-plugin" excludes everything that is provided on a running Flink cluster.

        b.2) "mvn clean package -Pbuild-jar" -> This will also create a fat-jar, but with much
                nicer dependency exclusion handling. This approach is preferred and leads to
                much cleaner jar files.

尝试使用最新版本的 avro

<dependency>
  <groupId>org.apache.avro</groupId>
  <artifactId>avro</artifactId>
  <version>1.8.2</version>
</dependency>

请尝试将 avro jar 放在 /lib 文件夹中。
