Steve Loughran updated HADOOP-19470:
------------------------------------
    Description: 
S3A: region resolution within AWS infra always goes to us-east-2

I think this is new to the V2 SDK, or at least our region logic there.
When you try to connect to a bucket without specifying the region, then even if 
you're running in the same region of the store a

While Machine configurations should ideally have the fs.s3a.endpoint.region 
setting configured, that information is actually pro

This is actually included in the default region chain according to the SDK docs 
"If running in EC2, check the EC2 metadata servi

# cross region access is being checked for first.
# the region chain we are setting off doesn't check the EC2 metadata service.

The SDK region chain does do the right thing within AWS infra. How do we 
restore that while still supporting remote deployments?
