Regarding the comparison between Hive and traditional data warehouse, which of the following description is wrong?

B . Because Hive is based on a big data platform, query efficiency is faster than traditional data warehouses.
C . Hive metadata storage is independent of data storage, which decouples metadata and data with high flexibility, while traditional data warehouse data has a single application and low flexibility.
D . Because Hive’s data is stored in HDFS, it can guarantee high data tolerance and high reliability.
