Steve Loughran commented on HADOOP-13560:
-----------------------------------------
Updated patch; tested s3a ireland
Uses fs.s3a.fast.upload as the switch to enable the new block output stream.
This makes it consistent with its (now deleted) predecessor; that is
un-deprecated, with all configuration options changed to use fast.upload in
their names; FAST_UPLOAD in their fieldnames.
I've tried to document all this, and add a new section on tuning queue sizes.

> An AWS SDK [issue|https://github.com/aws/aws-sdk-java/issues/367] highlights
> that metadata isn't copied on large copies.
> 1. Add a test to do that large copy/rname and verify that the copy really
> works
> 2. Verify that metadata makes it over.
> Verifying large file rename is important on its own, as it is needed for very
> large commit operations for committers using rename
