Depending on where they are exported, these methods are divided into three types: (1), export to the local file system; (2), export to HDFs; (3), export to another table in hive.

Hive Integrated HBase principle Hive is a data Warehouse tool based on Hadoop that maps structured data files to a database table and provides complete SQL query functionality that translates SQL statements into MapReduce tasks. The advantage is that the learning cost is low, the simple mapreduce statistic can be realized quickly by SQL statement, and it is very suitable for the statistic analysis of data
