YARN Optimizier

The Pulse YARN Optimizer enhances YARN cluster performance by intelligently optimizing memory allocation and CPU utilization across YARN applications.

This enables you to:

• Optimize YARN resource utilization by balancing memory and CPU across all nodes
• Enhance cluster performance by accelerating job execution and reducing processing time
• Increase job concurrency through efficient resource scheduling
• Reduce job queuing delays by preventing NodeManager bottlenecks
• Lower infrastructure costs by maximizing existing capacity
• Automate optimization using real-time monitoring and intelligent algorithms for continuous improvement.

Before You Begin

Before using the optimizer, ensure that the following components are deployed and enabled:

• YARN Optimizer Service and Alfred Service: required to process, analyze, and store optimization data and application fingerprints.
• YARN Metrics Agent: collects real-time metrics from cluster nodes for optimization analysis.
• Fingerprinting: must be enabled to capture and process application-level performance data.

For detailed steps, see Deploy Yarn Optimizer.
