Managing Device Plug-ins (Technical Preview)
Hortonworks Data Platform (HDP) 3.x releases before 3.1.4 supported the YARN GPU/FPGA device plug-in by writing custom code. Implementing such a device plug-in required knowledge of YARN integration and internal configuration related to NodeManager.
Starting with HDP 3.1.4, the plug-in framework simplifies the development process with minimal YARN configuration parameters and provides a more flexible way to integrate with YARN.
