extractBucketName

public static String extractBucketName(URI uri)

Helper function used to work around the fact that if you use an S3 bucket with an '_' that java.net.URI behaves differently and sets the host value to null whereas S3 buckets without '_' have a properly set host field. '_' is only allowed in S3 bucket names in us-east-1.

Parameters:

uri - The URI from which to extract a host value.

Returns:

The host value where uri.getAuthority() is used when uri.getHost() returns null as long as no UserInfo is present.

Throws:

IllegalArgumentException - If the bucket cannot be determined from the URI.

getFileSystemStats
