我在尝试使用flink的StreamingFileLink将文件放入azure datalake gen 2时遇到问题，我正在使用core-site.xml和hadoop批量格式，我正在尝试使用abfss://格式复制到我的datalake（也可以使用abfs://）

java.lang.UnsupportedOperationException: Recoverable writers on Hadoop are only supported for HDFS

我阅读了官方文件，潜入图书馆，问题就在这里：https://github.com/apache/flink/blob/master/flink-filesystems/flink-hadoop-fs/src/main/java/org/apache/flink/runtime/fs/hdfs/hadooprecoverablewriter.java#l60

public HadoopRecoverableWriter(org.apache.hadoop.fs.FileSystem fs) {
        this.fs = checkNotNull(fs);

        // This writer is only supported on a subset of file systems
        if (!"hdfs".equalsIgnoreCase(fs.getScheme())) {
            throw new UnsupportedOperationException(
                    "Recoverable writers on Hadoop are only supported for HDFS");
        }

这是我的core-site.xml

<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

<configuration>
  <property>
    <name>fs.azure.account.auth.type.ADLS_ACCOUNT_NAME.dfs.core.windows.net</name>
    <value>SharedKey</value>
    <description>
    It is inferred by the url

  </property>

  <property>
    <name>fs.azure.account.key.ADLS_ACCOUNT_NAME.dfs.core.windows.net</name>
    <value>ADLS_KEY</value>
    <description>
    </description>
  </property>

  <property>
    <name>fs.azure.createRemoteFileSystemDuringInitialization</name>
    <value>true</value>
  </property>

  <property>
    <name>fs.azure.always.use.https</name>
    <value>true</value>
  </property>

</configuration>

任何人都通过了这个问题，或者是扩展abfss/abfs的问题。
