What is Big Data Sqoop?
Sqoop (SQL-to-Hadoop) is one of the most popular Big Data tools that leverages the competency to haul out data from a non-Hadoop data store by transforming information into a form that can be easily accessed and used by Big Data Hadoop, to then upload it into HDFS. This process is most commonly known as ETL, for Extract, Transform, and Load.
While loading information into Big Data Hadoop is crucial for using MapReduce, it is equally critical to withdraw it from Big Data Hadoop, into an external data source for better usage in other types of applications.
Although it is sometimes imperative to migrate information as real-time big data analytics, it is also important to load and unload data in bulk quantities. It works as simple as this - you chip in Big Data Sqoop commands into the interpreter and all of it are executed one at a time.
