Aaron Fabbri commented on HADOOP-15040: --------------------------------------- Doing some testing with latest SDK 1.11.271 today. Looking through AWS SDK [change log|https://github.com/aws/aws-sdk-java/blob/master/CHANGELOG.md], only notice one change that might affect us when we upgrade from current version (1.11.199): - doesBucketExist() is now deprecated and there is a new V2 method that does not assume 403 forbidden implies the bucket exists (it does not).
