我正在使用齐柏林飞艇笔记本将数据帧保存在s3中。
df=spark.sql("select * from person")
df.write.mode('overwrite').option("header", "true").csv("s3a://file/location/")
我在齐柏林飞艇输出中出错:

但是当我检查Spark UI
时,作业成功完成。然后,我检查了S3 console
,数据被写入那里。
当我使用pyspark console
运行相同的代码时,其运行成功。
请帮助我解决齐柏林飞艇的问题。
我也检查了其他links,但没有帮助
编辑:
解决方案:将URL从s3a更改为s3时,它可以正常工作。请 帮助我。
答案 0 :(得分:2)
似乎在创建零字节_SUCCESS
标记时失败。
无论如何:这是有争议的。
FileOutputCommitter
进行的没有一致性层的直接目标。对于AWS EMR,它是“一致的EMR”;对于S3A,它是S3Guard,甚至更好,请在Hadoop 3.1中使用S3A提交程序。
没有这些,一切似乎都可以正常工作,但是每隔3次,S3中的清单不一致都会导致丢失其中一个工作人员创建的数据,从而导致最终结果中的数据少于预期的,并且没有任何结果被报告,因为没有人注意到这一点
我没有弥补。如果您想了解详细信息,请查看HADOOP-13345 HADOOP-13786和A Zero-Rename Committer。
