通过 Spark runner 和 HDFS 的 Apache Beam 字数统计示例失败并显示 "Failed to serialize and deserialize property"

Question

我正在尝试运行 Spark v1 上的 Apache Beam v2.0.0 字数统计示例。6.x（通过 Yarn v2.7.3），以便它读取和写入 HDFS（v2 .7.3).

目前，我通过以下命令提交作业：

bin/spark-submit --class org.apache.beam.examples.WordCount \
  --master yarn --deploy-mode cluster \
  test/word-count-beam-1.0-SNAPSHOT.jar \
    --inputFile=hdfs://test/input/* \
    --output=hdfs://test/output \
    --runner=SparkRunner --sparkMaster=yarn

不幸的是，作业失败并出现以下异常：

Failed to serialize and deserialize property 'hdfsConfiguration' with value '[Configuration: /usr/hdp/current/hadoop-client/conf/core-site.xml, /usr/hdp/current/hadoop-client/conf/hdfs-site.xml]'

这里是完整的堆栈跟踪：

有人知道如何解决这个问题吗？

我遇到了同样的问题。

java.util.ServiceLoader.load(com.fasterxml.jackson.databind.‌Module.class)中加载的模块是：

DefaultScalaModule
HadoopFileSystemModule
ParanamerModule

问题出在 dfsConfiguration 属性类型 ArrayList<Configuration>。

在 spark runner 配置文件的 jackson-module-scala 依赖项中排除 paranamer 依赖项有助于：

 <profiles>
     <profile>
        <id>spark-runner</id>
        <dependencies>
            ...
            <dependency>
                <groupId>com.fasterxml.jackson.module</groupId>
                <artifactId>jackson-module-scala_2.10</artifactId>
                <version>2.8.8</version>
                <scope>runtime</scope>
                <exclusions>
                    <exclusion>
                        <groupId>com.fasterxml.jackson.module</groupId>
                        <artifactId>jackson-module-paranamer</artifactId>
                    </exclusion>
                </exclusions>
            </dependency>
            ...
        </dependencies>
    </profile>
</profiles>

ParanamerModule 检查属性注释并且对 ArrayList 构造函数失败，但它是可选的。
