Setting up and Running Sqoop on our Hadoop Installation.
Apache Sqoop is a tool designed for efficiently transferring bulk data between Apache Hadoop and structured datastores such as relational databases. You can use Sqoop to import data from external structured datastores into the Hadoop Distributed File System (HDFS) or related systems such as Hive and HBase. Conversely, you can use Sqoop to extract data from Hadoop and export it to external structured datastores such as relational databases and enterprise data warehouses. While it is sometimes necessary to move the data in real time, it is most often necessary to load or unload data in bulk. Like Pig, Sqoop is a command-line interpreter. You type Sqoop commands into the interpreter and they are executed one at a time. Four key features are found in Sqoop: Bulk import: Sqoop can import individual tables or entire databases into HDFS. The data is stored in the native directories and files in the HDFS file system. Direct input: Sqoop can import and map SQL (relational) databas...
