Node Labeling

Node Labeling

Node labels divide a cluster into partitions. Each partition is a collection of nodes that have specific characteristics.
For example, you label the nodes in the cluster that process data faster compared to other nodes. You might use a label such as
fast
. The nodes that have the label
fast
represent a partition of the Hadoop cluster. Nodes that are not labeled belong to the default partition.
After you label the nodes in the cluster, you can assign the node labels to YARN queues. The jobs in queues run on the nodes that have the node label.
You can also use the node labels to configure the Blaze engine. When you use node labels to configure the Blaze engine, you specify the nodes on the Hadoop cluster where the Blaze engine starts.
