             Summary: [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
            Reporter: Gabor Bota
            Assignee: Gabor Bota


Set the value of fs.s3a.bucket.probe to 0 in the code-default.xml.
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.
