Stored Procedures
Stored procedures are function-like interfaces that extend the functionality of the connector beyond simple SELECT operations with HDFS.
Stored procedures accept a list of parameters, perform their intended function, and then return any relevant response data from HDFS, along with an indication of whether the procedure succeeded or failed.
