An open source tool that facilitates bi-directional data transfer between HDFS and RDBMS.
Open Database Connectivity is a database independent CLI specification for accessing DBMS via a C programming language API. The ODBC Application, Driver Manager and Driver are the main players. Driver Manager acts as a factory that loads a driver from the various others available; as requested by the Application. The actual driver is never exposed to the Application, every call goes via Driver Manager.
