根据此announcement，Amazon S3文件大小限制应该为5T，但是在上传5G文件时出现以下错误
'/mahler%2Fparquet%2Fpageview%2Fall-2014-2000%2F_temporary%2F_attempt_201410112050_0009_r_000221_2222%2Fpart-r-222.parquet' XML Error Message:
<?xml version="1.0" encoding="UTF-8"?>
<Error>
<Code>EntityTooLarge</Code>
<Message>Your proposed upload exceeds the maximum allowed size</Message>
<ProposedSize>5374138340</ProposedSize>
...
<MaxSizeAllowed>5368709120</MaxSizeAllowed>
</Error>
这使得S3似乎只接受5G上传。我正在使用Apache Spark SQL使用
SchemRDD.saveAsParquetFile方法写出一个Parquet数据集。完整的堆栈跟踪为

上传限制仍为5T吗？如果这是为什么我会收到此错误，该如何解决？
最佳答案
对象大小限制为5 TB。上载大小仍为5 GB，如手册中所述:
http://docs.aws.amazon.com/AmazonS3/latest/dev/UploadingObjects.html
完成分段上传后，S3会验证并重组各个部分，然后在S3中拥有一个最大5TB的对象，可以将其作为单个实体下载，并带有单个HTTP GET请求...但是可以上传即使您小于5GB的文件，它的速度也可能要快得多，因为您可以并行上传部件，甚至重试第一次尝试未成功上传的部件。
关于amazon-s3 - 将5G文件上传到Amazon S3时出现EntityTooLarge错误，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/26319815/
