-------------------------------------
Summary: Ignore x-emc-* headers when copying an Amazon S3 object
Key: HADOOP-11687
URL: https://issues.apache.org/jira/browse/HADOOP-11687
Project: Hadoop Common
Issue Type: Bug
Components: fs/s3
Affects Versions: 2.7.0
Reporter: Denis Jannot
The EMC ViPR/ECS object storage platform uses proprietary headers starting by
x-emc-* (like Amazon does with x-amz-*).
Headers starting by x-emc-* should be included in the signature computation,
but it's not done by the Amazon S3 Java SDK (it's done by the EMC S3 SDK).
When s3a copy an object it copies all the headers, but when the object includes
x-emc-* headers, it generates a signature mismatch.
Removing the x-emc-* headers from the copy would allow s3a to be compatible
with the EMC ViPR/ECS object storage platform.
Removing the x-* which aren't x-amz-* headers from the copy would allow s3a to
be compatible with any object storage platform which is using proprietary
headers
