database, a NoSQL database that provides the ability to read and write like other databases, Hadoop does not meet real-time needs, and HBase is ready to meet. If you need real-time access to some data, put it into hbase.You can use hive as a static data warehouse, HBase as the data store, and put some data that will change. In hive, the normal table is stored in HDFs, and you can specify the data storage location by creating external table appearance
