JDBC Driver for HDFS

Build 22.0.8462

Stored Procedures

Stored procedures are function-like interfaces that extend the functionality of the driver beyond simple SELECT operations with HDFS.

Stored procedures accept a list of parameters, perform their intended function, and then return, if applicable, any relevant response data from HDFS, along with an indication of whether the procedure succeeded or failed.
