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).
How Low Can Your Blood Glucose Level Go Safely? Low blood sugar can result in weakness, confusion, headache, irritability, excessive hunger, excessive sweating or fatigue. The normal range of blood sugar is 80 - 120 mg/dL (milligrams per deciliter) in the morning (after fasting for at least 8 hours). Normally, if the level drops below 70 mg/dL, the person is said to suffer from hypoglycemia or low blood sugar levels.
