使用 Spark insertInto 时出现 FileAlreadyExistsException

【中文标题】使用 Spark insertInto 时出现 FileAlreadyExistsException【英文标题】：FileAlreadyExistsException while using Spark insertInto 【发布时间】：2020-09-18 02:09:53 【问题描述】：

我使用以下代码通过 pyspark Insertinto 函数将数据帧写入配置单元分区表。

spark.conf.set("spark.sql.sources.partitionOverwriteMode", "DYNAMIC")
df.write.mode("overwrite").insertInto(table, overwrite=True)

当集群运行其他一些繁重的工作时。它有 1/3 的错误概率。

我认为这可能发生在任务似乎失败但实际上并没有失败并且 yarn 启动了另一个任务来运行此作业时。所以两个任务冲突。
