Mujtaba Chohan commented on PHOENIX-3174: ----------------------------------------- [~samarthjain] After upgrading from 4.7 -> 4.9 and then restoring SYSTEM.CATALOG snapshot, re-connecting 4.9 client leads to the following error (all default Phoenix properties used): {noformat} Error: Operation not allowed since cluster hasn't been upgraded. Call EXECUTE UPGRADE. (state=INT13,code=2011) org.apache.phoenix.exception.UpgradeRequiredException: Operation not allowed since cluster hasn't been upgraded.
