About Sqoop
Now, let us share the primary information of the Sqoop concept. The traditional application management system, and the interaction of applications with the relational database using the database RDBMS. This RDBMS is one of the sources that generate the Big Data. Such Big Data generated by the RDBMS, is then stored in Relational Database Servers in the precise structure. When Big Data storages and analyzers such as MapReduce, HBase, Hive, Cassandra, Pig, etc., of the Hadoop ecosystem. Therefore, Sqoop occupies a place in the Hadoop ecosystem to provide possible interaction between the relational database server and Hadoop’s HDFS.
