Steve Loughran commented on HADOOP-13560:
-----------------------------------------
small files of a few tens of MB work; bigger files timeouts start to happen;
need to make sure code is resilient to this and reports problems meaningfully
> make sure s3 blob >5GB files copies, with metadata

> Key: HADOOP-13560

> Project: Hadoop Common
> Issue Type: Sub-task

> Reporter: Steve Loughran
> Priority: Minor
>
> 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
> 1. 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
