> 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.
