If a customer makes an IT decision as big as running Hadoop or RDBMS with S3 as storage ... but does not consult at least a Associate level AWS Certified architect (who are doke a dozen) for at least one day worth of advice which is probably a couple of hundred dollars at most ... Can we really blame AWS? I am sure none of official AWS documentations or examples show such an architecture. ---- Amazon EMR can run Hadoop and use Amazon S3 as storage via EMR FS. "S3 mountpoints" are a feature specifically for workloads that need to see S3 as a file system. For block storage workloads there is EBS and EFS and FSx that AWS heavily advertises.
