> [s3a] Disable bucket existence check - set fs.s3a.bucket.probe to 0
> -------------------------------------------------------------------
>
> Key: HADOOP-17454
> URL: https://issues.apache.org/jira/browse/HADOOP-17454
> Project: Hadoop Common
> Issue Type: Improvement
> Affects Versions: 3.3.0
> Reporter: Gabor Bota
> Assignee: Gabor Bota
> Priority: Major
>
> Set the value of fs.s3a.bucket.probe to 0 by default.
> Bucket existence checks are done in the initialization phase of the
> S3AFileSystem. It's not required to run this check: the operation itself will
> fail if the bucket does not exist instead of the check.
> Some points on why do we want to set this to 0:
> * When it's set to 0, bucket existence checks won't be done during
> initialization thus making it faster.
> * Avoid the additional one or two requests on the bucket root, so the user
> does not need rights to read or list that folder.
