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

Hive is based on HDFS storage. In theory, the amount of storage can be expanded indefinitely, while the traditional data warehouse storage capacity has an upper limit.

Because Hive is based on a big data platform, query efficiency is faster than traditional data warehouses.

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.

Because Hive's data is stored in HDFS, it can guarantee high data tolerance and high reliability.

ZooKeeper uses a custom atomic message protocol to ensure the consistency of node data throughout the system.

The ZooKeeper cluster elects the Leader role at startup.

After receiving the data change request, the Leader node writes the disk first and then writes the memory.

Question 23 of 25

24. In the Spark SQL table, there are often many small files (the size is much smaller than the HDFS block size). In this case, Spark will start more Task to process these small files.
