将Blob连接到Spark失败

Question

我正在尝试将Hortonworks 2.4发行版中的spark连接到Azure Blob存储，但我收到错误消息"wasb文件系统无法识别“。我检查了一下，很多人建议下载azure-sdk-for-java并创建包。

我正在尝试使用mvn创建包，但同时运行mvn测试和mvn包；测试时进程挂起。没有给出错误，只是没有返回任何东西。我更改了testconfiguration.xml以反映我的blob帐户名。下面是我得到的日志文件。

要获得jars，还需要做些什么吗？

根据您的描述，我不确定您是否在项目中正确配置了存储配置。因此，我建议您按照以下步骤检查您的配置：

1.创建你的Azure存储帐户，并在core-site.xml中将其设置为以下格式：

<property>
  <name>fs.azure.account.key.youraccount.blob.core.windows.net</name>
  <value>YOUR ACCESS KEY</value>
</property>

2.重启HDP服务，使用Hadoop fs –ls wasb://**.blob.core.windows.net/列出容器中的文件。

我强烈建议你可以参考这个博客how-to-configure-hortonworks-hdp-to-access-azure-windows-storage和官方document。

同时，@Yuval提供了关于如何使用Java SDK连接到Azure blob的很好的示例。
