I chuckled when I read "We have a legacy data warehouse based in Hive and Elastic MapReduce, with backing data stores in S3.". I guess things have come full circle. It wasn't long ago that a relational database solution would have been "legacy".

But "legacy" is not only when technology gets old, but also when solutions get old. Maybe it was just a bad solution and they are moving it to a new solution, not necessarily a new platform.

I did too, mainly because S3 + Hadoop isn't going to provide the locality and speed that HDFS would. I don't think it's a fair comparison.
