---------------------------------------
Summary: multipart/huge file upload tests to look at checksums
returned
Key: HADOOP-16313
URL: https://issues.apache.org/jira/browse/HADOOP-16313
Project: Hadoop Common
Issue Type: Sub-task
Components: fs/s3, test
Affects Versions: 3.2.0
Reporter: Steve Loughran
Apparently some third party S3-API object stores have empty etags for multipart
uploads.
We don't have any tests to explore this (just small file uploads).
Proposed
*set {{fs.s3a.etag.checksum.enabled"}} before huge file, MPU and committer tests
* warn (fail?) if nothing comes back.
If true, it means that the store isn't going to be detect changes to a large
file during copy/read
