我正在尝试将StreamingFileLink连接到azure blob存储。目前文档中没有提到azure，但我希望它能与文件系统抽象一起工作。
在分析错误之后，我假设这个特性现在不在azure blob存储的范围之内。
现在我想确保我没有犯任何错误，如果有办法让它工作的话，我会很感激你的指点。
到目前为止我发现：
这是我看到的例外：

现在似乎缺少hadooprecoverablewriter类方法
但是在flink azure fs hadoop存储库中，我可以在pom.xml中找到这个

<!-- shade Flink's Hadoop FS adapter classes  -->
<relocation>
    <pattern>org.apache.flink.runtime.fs.hdfs</pattern>
    <shadedPattern>org.apache.flink.fs.azure.common.hadoop</shadedPattern>
</relocation>

阴影包包含了这个类。
现在我查看了flink-azure-fs-hadoop-1.10.0.jar和shaded包的内容，可恢复编写器不见了：

HadoopBlockLocation.class
HadoopDataInputStream.class
HadoopDataOutputStream.class
HadoopFileStatus.class
HadoopFileSystem.class
HadoopFsFactory.class
HadoopFsRecoverable.class

更多的挖掘显示pom.xml shade部分中实际上有一个过滤器，它排除了recoverablewriter。
