YARN Node Labels

Description: Node Labels in YARN (Yet Another Resource Negotiator) are a fundamental feature that allows categorizing nodes in a cluster based on their specific capabilities and characteristics. These labels facilitate resource management by enabling administrators to assign jobs to nodes that meet certain criteria, thereby optimizing resource usage and improving overall system performance. For instance, a node can be labeled as ‘GPU’ if it has graphics processing capabilities, while another can be labeled as ‘high-memory’ if it has a large amount of RAM. This classification not only helps administrators better organize resources but also allows application developers to specify more precise resource requirements when submitting jobs to the cluster. Node labels are particularly useful in environments where multiple types of workloads are running, as they ensure that tasks are directed to the most suitable nodes, resulting in greater efficiency and better utilization of available resources.
