Welcome to Phoenix... where the cardinal rule is if you are going to use Phoenix, then for that table, don't look at it or use it directly from the HBase API. What you are seeing is pretty normal.

Remember, use Phoenix only for Phoenix tables and you'll be all right. 🙂 Good luck and happy Hadooping/HBasing! ... View more
