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).

A healthy blood sugar level is between 70 and 130 milligrams per deciliter (mg/dL) before meals and less than 180 mg/dL one to two hours after the start of a meal, according to the American Diabetes Association. Three tests are commonly used to measure blood sugar levels.
