>             Project: Hadoop Common
>          Issue Type: Sub-task
>          Components: fs/s3
>    Affects Versions: 3.0.0
>            Reporter: Steve Loughran
>            Priority: Minor

> [~rdblue] reports sometimes he sees corrupt data on S3. Given MD5 checks from upload to S3, its likelier to have happened in VM RAM, HDD or nearby.
> If the MD5 checksum for each block was built up as data was written to it, and checked against the etag RAM/HDD storage of the saved blocks could be removed as sources of corruption
> The obvious place would be {{org.apache.hadoop.fs.s3a.S3ADataBlocks.DataBlock}}
