Functioning of Sqoop
Let's get into a bit more detail on the actual working of Sqoop in this section. When a command is entered in the command line, these in turn execute a map task to connect to the desired RDBMS (using appropriate connector) and then retrieve the required/relevant data. After the map task, it hands over the data to the reduce task, which has the responsibility of persisting this retrieved data to HDFS/HBase/Hive.
