Enabling ZooKeeper Based State Store

About this task

By default, the Resource Manager stores its state in the MapR-FS. However, you can use the Zookeeper based state store instead. To configure the ResourceManager to use the Zookeeper state store:

Procedure

Set the value of yarn.resourcemanager.store.class to org.apache.hadoop.yarn.server.resourcemanager.recovery.ZKRMStateStore in the yarn-site.xml.
Set the value of yarn.resourcemanager.zk-address to a comma-separated list of host:port pairs for each ZooKeeper server used by the ResourceManager. This property needs to be set in yarn-site.xml.
