SQOOP is an open source which is the product of Apache. SQOOP stands for SQL to Hadoop. It is the tool which is the specially designed to transfer data between Hadoop and RDBMS like SQL Server, MySQL, Oracle etc.
SQOOP is basically command based interface so we use import command to transfer RDBMS data to Hadoop and Export command to transfer data back in RDBMS.
We use sqoop help command to see all the commands used in sqoop.
