The beauty of Apache Hadoop lies in its ability to work with multiple data formats. HDFS can reliably store information flowing from a variety of data sources, whereas Hadoop requires external interfaces to interact with storage repositories outside of HDFS. Sqoop helps you to address part of this problem by allowing users to extract structured data from a relational database to Apache Hadoop. Similarly, raw data can be processed in Hadoop, and the final results can be shared with traditional databases thanks to Sqoop's bidirectional interfacing capabilities.
Sqoop can be downloaded from the Apache site directly, and it supports client-server-based architecture. A server can be installed on one of the nodes, which then acts as a gateway for all Sqoop activities. A client can be installed on any machine, which will eventually connect with the server...
