GCS Hadoop连接器错误：ClassNotFoundException：com.google.api.client.http.HttpRequestInitializer ls：方案gs没有文件系统

如何解决GCS Hadoop连接器错误：ClassNotFoundException：com.google.api.client.http.HttpRequestInitializer ls：方案gs没有文件系统

我正在尝试在本地Ubuntu 20.04上设置hadoop-connectors并运行测试命令hadoop fs -ls gs://my-bucket，但我不断收到如下错误：

$ hadoop fs -ls gs://my-bucket
2020-08-22 03:29:06,976 WARN fs.FileSystem: Cannot load filesystem: java.util.ServiceConfigurationError: org.apache.hadoop.fs.FileSystem: com.google.cloud.hadoop.fs.gcs.GoogleHadoopFileSystem Unable to get public no-arg constructor
2020-08-22 03:29:06,977 WARN fs.FileSystem: java.lang.NoClassDefFoundError: com/google/api/client/http/HttpRequestInitializer
2020-08-22 03:29:06,977 WARN fs.FileSystem: java.lang.ClassNotFoundException: com.google.api.client.http.HttpRequestInitializer
ls: No FileSystem for scheme "gs"

请注意，我可以使用gsutil ls gs://my-bucket访问存储桶。

我已经从here下载了gcs-connector-hadoop3-latest.jar并将其放在/usr/local/hadoop/share/hadoop/common/lib中。我希望这是此jar文件的正确位置？

我已经为core-site.xml配置了列出的here属性，并且还为我的服务帐户密钥文件设置了GOOGLE_APPLICATION_CREDENTIALS。在hadoop-env.sh中，我已导出

export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64/ 
export HADOOP_CLASSPATH+="$HADOOP_CLASSPATH:$HADOOP_HOME/share/hadoop/common/lib/*.jar:$HADOOP_HOME/lib/*.jar"

不确定我是否正确设置了HADOOP_CLASSPATH，并且hadoop是否能识别/usr/local/hadoop/share/hadoop/common/lib中的jar文件？与/usr/local/hadoop/lib有什么区别？

以下是core-site.xml的相关内容：

解决方法

重新启动似乎可以解决问题。重新启动后，命令ndk.abiFilters 'arm64-v8a','x86_64' 将起作用，并按预期方式列出存储桶的内容。

感谢@IgorDvorzhak提供以下命令：hadoop fs -ls gs://my-bucket检查是否可以找到hadoop classpath --glob。我用过：

gcs-connector-hadoop3-latest.jar
