I would strongly disagree. In 1995 relational theory and practice was well understood by a large set of developers and had stable, well documented implementations. Raw Hadoop and the associated computational model is not at that level of stability, documentation and usability. In addition the relational model applies to many business problems, large and small. Hadoop is generally applicable and cost efficient only for larger, more complex problems.
you can't strongly anything as an AC, sorry buddy
If you're not careful, you're going to catch something.
