Steve Loughran resolved HADOOP-15087.
-------------------------------------
Resolution: Duplicate
this is what the committers and the distcp -Xdirect options are for
> S3A to support writing directly to the destination dir without creating temp
> directory to avoid rename

> Key: HADOOP-15087
> URL: https://issues.apache.org/jira/browse/HADOOP-15087
> Project: Hadoop Common
> Issue Type: New Feature
> Components: fs/s3
> Affects Versions: 3.0.0
> Reporter: Yonger
> Priority: Major
>
> Rename in workloads like Teragen/Terasort who use Hadoop default
> outputcommitters really hurt performance a lot.
> Stocator announce it doesn't create the temporary directories any all, and
> still preserves Hadoop's fault tolerance. I add a switch when creating file
> via integrating it's code into s3a, I got 5x performance gain in Teragen and
> 15% performance improvement in Terasort.
