Question

Under the YARN/MRv2 framework, the JobTracker functions are split into which two daemons?

A. JobMaster
B. ResourceManager
C. ScheduleManager
D. ApplicationMaster

Answer 1

In the YARN/MRv2 framework, the Job Tracker functions are divided between the Resource Manager, which handles resource management and task scheduling, and the Application Master, which manages application lifecycles and task execution.

Step-by-step explanation:

Under the YARN/MRv2 framework, the Job Tracker functions are split into two daemons: the Resource Manager and the Application Master. The Resource Manager is responsible for managing the cluster resources and scheduling tasks across the available nodes. On the other hand, the Application Master is responsible for managing the lifecycle of a specific application, negotiating resources with the Resource Manager, and working with the Node Managers to execute and monitor the tasks.
