Sqoop-Based Connector: A Sqoop-Based Connector allows you to establish a connection between Sqoop, a data transfer tool for Hadoop, and other systems or databases. It enables you to efficiently import and export data between Hadoop and various data sources such as relational databases or mainframes. Measuring this skill in the test ensures that candidates have the knowledge to effectively utilize connectors to integrate Sqoop with different systems.
Disk I/O and Network I/O: Disk I/O refers to the reading and writing of data to and from storage devices, while Network I/O involves the transmission of data over a network. Both skills are crucial in the context of Sqoop as they directly impact the performance and efficiency of data transfers. Measuring these skills ensures that candidates understand how to optimize the usage of disk and network resources when using Sqoop for importing and exporting data.
MySQL Databases: MySQL is a widely used open-source relational database management system. In the context of Sqoop, knowing how to work with MySQL databases is essential as it allows seamless integration between Hadoop and MySQL. Measuring this skill ensures that candidates can properly configure and interact with MySQL databases using Sqoop commands.
Database Tables: Database tables are structured sets of data organized into rows and columns. In the context of Sqoop, understanding how to interact with database tables is critical as it enables the import and export of data between Hadoop and relational databases. Measuring this skill ensures that candidates are proficient in handling various operations related to database tables using Sqoop.
Sqoop Import and Export Commands: Sqoop provides a set of import and export commands that allow for data transfer between Hadoop and external systems or databases. Knowing how to effectively use these commands is vital when working with Sqoop. Measuring this skill ensures that candidates have a solid understanding of the different import and export options provided by Sqoop, enabling them to efficiently move data in and out of Hadoop.
