Enabling ZooKeeper Based State Store

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