But there are some challenges with it in its current state. Correct me if I’m wrong, but I believe it is nowhere near supporting SQL92, has minimal metadata, and does not leverage Hadoop workflows or HDFS failover. (It’s a separate engine embedded in Hadoop that you query directly.) With Yarn, HCatalog, and other things, these will be addressed, but I’m wondering whether any companies are successfully using IMpala right now, and whether they might be better served parsing and dumping the data into a DBMS and then analyzing it there. There is a huge “Hadoop is a silver bullet” mentality out there right now. At the same time, I do see DW managers questioning whether it makes to move data into a DW if it’s already in Hadoop. That’s certainly a legitimate question and one that could turn our industry on its head.
