The answer by Matthieu Lieber describes how you can load data to a parquet table. Couple of things before you post your next question. Please mention what version you are using. Parquet was not natively supported in Hive versions prior to 0.13 and you need to add some explicit jars to get the functionality. Please add the logs/error messages. It fails is a vague description of the error and it makes things difficult to debug. The way you are doing the data load seems OK and it should work.
A normal fasting (no food for eight hours) blood sugar level is between 70 and 99 mg/dl (between 3.9 and 5.5 mmol/l). A normal blood sugar level two hours after eating is less than 140 mg/dl (7.7 mmol/l). However, lower than that would be better. Some experts say shoot for 120 (or 6.6).
Normal blood sugar varies from person to person, but a normal range for fasting blood sugar (the amount of glucose in your blood six to eight hours after a meal) is between 70 and 100 milligrams per deciliter. For most individuals, the level of glucose in the blood rises after meals. A normal blood-sugar range after eating is between 135 and 140 milligrams per deciliter. These variations in blood-sugar levels, both before and after meals, are normal and reflect the way that glucose is absorbed and stored in the body.
