Updating ResourceManager Ports

To simplify the failover configurations in the yarn-site.xml file, Warden maintains the list of ResourceManager ports in the warden.resourcemanager.conf file. For a list of the default port numbers, see Ports Used by HPE Ezmeral Data Fabric Software. If you want to edit the default ResourceManager ports, edit the warden.resourcemanager.conf file and the yarn-site.xml file on each ResourceManager node.

Note: If each node requires different ResourceManager ports, you must maintain a separate yarn-site.xml file for each node. Therefore, to you use Central Configuration, you must create a customized configuration file for each ResourceManager node in the cluster.

To update the port numbers, edit the values in the warden.resourcemanager.conf file and add the values in the yarn-site.xml file.

Open the warden.resourcemanager.conf file (/opt/mapr/conf/conf.d/warden.resourcemanager.conf).

Edit the port numbers, which are listed using the following format: service.extinfo.<port>= <port number>

Port Name	Property Name in warden.resourcemanager.conf
ResourceManager Scheduler RPC (for ApplicationMasters)	service.extinfo.SCHEDULER_PORT
ResourceManager Resource Tracker RPC (for NodeManagers)	service.extinfo.RESOURCETRACKER_PORT
ResourceManager Client RPC	service.port
ResourceManager Admin RPC	service.extinfo.ADMIN_PORT
ResourceManager Web UI (HTTP)	service.extinfo.WEBAPP_PORT
ResourceManager Web UI (HTTPS)	service.extinfo.WEBAPP_HTTPS_PORT

Open the yarn-site.xml file (/opt/mapr/hadoop/hadoop-2.x.x/etc/hadoop/yarn-site.xml).

For each port that you edited, add the associated property to the yarn-site.xml file:

Port Name	Property Name in yarn-site.xml
ResourceManager Scheduler RPC (for ApplicationMasters)	yarn.resourcemanager.scheduler.address
ResourceManager Resource Tracker RPC (for NodeManagers)	yarn.resourcemanager.resource-tracker.address
ResourceManager Client RPC	yarn.resourcemanager.address
ResourceManager Admin RPC	yarn.resourcemanager.admin.address
ResourceManager Web UI (HTTP)	yarn.resourcemanager.webapp.address
ResourceManager Web UI (HTTPS)	yarn.resourcemanager.webapp.https.address

For example, to update the port number for the ADMIN_PORT to 9000 on each node, enter the following in the yarn-site.xml file on each node:

<property>
   <name>yarn.resourcemanager.adminaddress</name>
   <value>10.10.30.140:9000</value>
</property>

Restart the Warden and the ResourceManager services.
