Scheduling and Node Labeling Configuration

Update the yarn-site.xml file on the domain environment to enable scheduling and node labeling in the Hadoop environment. Configure the following properties:
yarn.resourcemanager.scheduler.class
Defines the YARN scheduler that the Data Integration Service uses to assign resources on the cluster. 
<property>
    <name>yarn.resourcemanager.scheduler.class</name>
    <value><org.apache.hadoop.yarn.server.resourcemanager.scheduler.[Scheduler Type].[Scheduler Type]Scheduler></value>
</property>
For example: 
<property>
    <name>yarn.resourcemanager.scheduler.class</name>
    <value><org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.CapacityScheduler></value>
</property>
yarn.node-labels.enabled
Enables node labeling. 
<property>
    <name>yarn.node-labels.enabled</name>
    <value><TRUE></value>
</property>
yarn.node-labels.fs-store.root-dir
The HDFS location to update the node label dynamically. 
<property>
    <name>yarn.node-labels.fs-store.root-dir</name>
    <value><hdfs://[Node name]:[Port]/[Path to store]/[Node labels]/></value>
</property>
