The Sqoop tool connects to a relational database in a Hadoop environment and serves as a bridge to the hadoop storage system. It supports the import of multiple relational data sources and hive, hdfs, and hbase. Generally, relational data tables exist in the backup environment of the online environment. data needs to be imported every day. sqoop can import the entire table based on the amount of data per da

Label:First, what is Sqoop Sqoop is an open source tool that is used primarily in Hadoop (Hive) and traditional databases (MySQL, PostgreSQL ...) Data can be transferred from one relational database (such as MySQL, Oracle, Postgres, etc.) to the HDFs in Hadoop, or the data in HDFs can be directed into a relational database. Second, the characteristics of Sqoop On
