> URL: https://issues.apache.org/jira/browse/HADOOP-16711
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.2.1
> Reporter: Rajesh Balamohan
> Assignee: Mukund Thakur
> Priority: Minor
> Labels: performance
> Fix For: 3.3.0
>
> Attachments: HADOOP-16711.prelim.1.patch

>
> 1. in S3AFileSystem.initialize(), we check for the bucket existing with verifyBucketExists(), which calls s3.doesBucketExist(). But that doesn't check for auth issues.
> s3. doesBucketExistV2() does at validate credentials, and should be switched to. This will help things fail faster
> 2. For performance it would be good to skip verifyBuckets call during S3A filesystem init(). This would save a call to S3 during init method.
