I have not actually done this myself, but I can try to give you a general idea. Roughly the steps are to modify the capacity-scheduler.xml file, run yarn rmadmin -refreshQueues (not sure if you also have to start the RM or not -- maybe depends on what kinds of things you change). Then run yarn rmadmin -addToClusterNodeLabels label1,label2 and yarn rmadmin -replaceLabelsOnNode "node1,label1 node2,label2 ".
At a minimum, the changes to the capacity scheduler involve adding your labels to a queue. You may want to consider setting up a whole new queue for Accumulo, to guarantee it has space to run. The following properties should configure label1 and label2 for the default queue. I put the * there in the hopes it would still allow the queue to accept empty labels, but I'm not sure if that's the right way to do it. <property><name>yarn.scheduler.capacity.root.default.accessible-node-labels</name><value>*,label1,label2</value></property> <property><name>yarn.scheduler.capacity.root.default.accessible-node-labels.label1.capacity</name><value>20</value></property> <property><name>yarn.scheduler.capacity.root.default.accessible-node-labels.label2.capacity</name><value>80</value></property> Then when you submit your Slider cluster, add "yarn.label.expression": "label1" to your component(s) in the resources.json file. See also hadoop-yarn-project/hadoop-yarn/hadoop-yarn-applications/hadoop-yarn-applications-distributedshell/src/test/java/org/apache/hadoop/yarn/applications/distributedshell/TestDistributedShell.java that seems to set up a label for testing.
