The initial need for Sqoop to initialize data from the Library data table into HBase, the entire process needs to be automated to minimize human intervention. However, for historical reasons, there are two types of database (tables) in the character set format on the line, and the data imported into hbase needs to be stored uniformly in

Using Hadoop to analyze and process data requires loading the data into a cluster and combining it with other data in the enterprise production database. It is a challenge to load large chunks of data from production systems into Hadoop or to get data from map reduce applications in large clusters. Users must be aware of the details of ensuring data consistency, consuming production system resources, and supplying downstream pipeline data preprocessing. Using a script to transform data is ineffi

first, what is Sqoop?Sqoop is a bridge connecting traditional relational databases to Hadoop. It includes the following two areas:1. Import data from a relational database into Hadoop and its associated systems, such as Hive and HBase.2. Extract the data from the Hadoop system and export it to the relational database.Sqoop's core design idea is to use MapReduce t
