Sqoop (SQL-to-Hadoop) is a big data tool that offers the capability to extract data from non-Hadoop data stores, transform the data into a form usable by Hadoop, and then load the data into HDFS. This process is called ETL, for Extract, Transform, and Load. ... Like Pig, Sqoop is a command-line interpreter.

Unlike Relational Database Management System (RDBMS), we cannot call Hadoop a database, but it is more of a distributed file system that can store and process a huge volume of data sets across a cluster of computers. Hadoop has two major components: HDFS (Hadoop Distributed File System) and MapReduce.

Sqoop doesn't permit you to import, all at once, a relational table directly into an HBase table having multiple column families. To work around this limitation, you create the HBase table first and then execute two Sqoop import operations to finish the task.

Hive and HBase are two different Hadoop based technologies — Hive is an SQL-like engine that runs MapReduce jobs, and HBase is a NoSQL key/value database on Hadoop. ... Just like Google can be used for search and Facebook for social networking, Hive can be used for analytical queries while HBase for real-time querying.

Hadoop will not replace a data warehouse because the data and its platform are two non-equivalent layers in Data warehouse architecture. However, there is more probability of Hadoop replacing an equivalent data platform such as a relational database management system.
