It provides a hiveql language similar to SQL, this allows upper-layer data analysts to analyze massive data stored in HDFS without having to know too much about mapreduce. This feature has been widely welcomed. An important module in the overall hive framework is the execution module, which is implemented using the mapreduce computing framework in hadoop. Therefor
