Answer / Gautam Sinha
In Hadoop, the Job Tracker performs several actions, including:
1. Scheduling jobs for execution on data nodes based on resource availability and dependencies between jobs.
2. Assigning tasks to task trackers on different data nodes.
3. Monitoring the progress of running tasks and reporting their status back to the client.
4. Handling heartbeats from data nodes to ensure they are still alive and working correctly.
