在单个表上进行 Parllel 追加操作的情况下重命名 JSON 文件时_delta_log面临问题
RM 重新启动后恢复的尝试用户类引发异常：java.io.IOException：从 wasbs://
@.blob.core.windows.net/delta_table/_delta_log/.00000000000000000243.json.f0bf5c51-b7ae-4da8-931e-b1acc21170f5.tmp 重命名为 wasbs:// @.blob.core.windows.net/delta_table/_delta_log/00000000000000000243.json 失败。
这里我使用的是 0.5.0 版本的 delta ，请检查下面的堆栈跟踪

堆栈跟踪显示您使用了不正确的 LogStore 实现：HDFSLogStore。HDFSLogStore 是为 Hadoop 分布式文件系统 (HDFS( 构建的。
若要在 Delta Lake 中使用 Azure Blob 存储，应设置以下配置。
spark.delta.logStore.class=org.apache.spark.sql.delta.storage.AzureLogStore
有关完整说明，请参阅 https://docs.delta.io/latest/delta-storage.html#azure-blob-storage。
