Testing ResourceManager HA on a Single Node
Enable ResourceManagers to launch and explicitly set values specific to each
ResourceManager separately yarn-site.xml
file.
Test ResourceManager High Availability on a single node
To test ResourceManager HA on a single node (launch more than one ResourceManager on a single node),
you need to add the following settings in yarn-site.xml.
To enable ResourceManager "rm1" to launch:
<property> <name>yarn.resourcemanager.ha.id</name> <value>rm1</value> <description>If we want to launch more than one RM in single node, we need this configuration</description> </property>
To enable ResourceManager rm2
to launch:
<property> <name>yarn.resourcemanager.ha.id</name> <value>rm2</value> <description>If we want to launch more than one RM in single node, we need this configuration</description> </property>
You should also explicitly set values specific to each ResourceManager for the following properties separately in
yarn-site.xml
:
yarn.resourcemanager.address.<rm-id>
yarn.resourcemanager.scheduler.address.<rm-id>
yarn.resourcemanager.admin.address.<rm-id>
yarn.resourcemanager.resource#tracker.address.<rm-id>
yarn.resourcemanager.webapp.address.<rm-id>
For example:
<!-- RM1 Configs --> <property> <name>yarn.resourcemanager.address.rm1</name> <value>localhost:23140</value> </property> <property> <name>yarn.resourcemanager.scheduler.address.rm1</name> <value>localhost:23130</value> </property> <property> <name>yarn.resourcemanager.webapp.address.rm1</name> <value>localhost:23188</value> </property> <property> <name>yarn.resourcemanager.resource-tracker.address.rm1</name> <value>localhost:23125</value> </property> <property> <name>yarn.resourcemanager.admin.address.rm1</name> <value>localhost:23141</value> </property> <!-- RM2 configs --> <property> <name>yarn.resourcemanager.address.rm2</name> <value>localhost:33140</value> </property> <property> <name>yarn.resourcemanager.scheduler.address.rm2</name> <value>localhost:33130</value> </property> <property> <name>yarn.resourcemanager.webapp.address.rm2</name> <value>localhost:33188</value> </property> <property> <name>yarn.resourcemanager.resource-tracker.address.rm2</name> <value>localhost:33125</value> </property> <property> <name>yarn.resourcemanager.admin.address.rm2</name> <value>localhost:33141</value> </property>
