Description

{ClassCastException in S3GuardTool.checkMetadataStoreUri() during a run of ITestS3GuardToolDynamoDB.testDestroyFailsIfNoBucketNameOrDDBTableSet()

stack trace is lost, but cause is that the FS returned by newInstance() isn't an S3AFS, it's a local FS.

Irrespective of underlying cause, the s3guard tool code should check the class type and raise an exception including the FS URI on a mismatch.
