Get a thorough walkthrough of the different approaches to selecting, buying, and implementing a semantic layer for your analytics stack, and a checklist you can refer to as you start your search. I understand user had used ORC file instead of Parquet file format which may cause performance problem. Assuming that the discrepancy is not due to rounding errors, we conclude that at least one of Hive on MR3 and Presto is certainly unsound with respect to query 21.
