> MAPREDUCE-279 included bits and pieces of possible ZK integration for YARN's RM, but looks like it failed to complete it (for scalability reasons? etc?) and there seems to be no JIRA tracking this feature that has been already claimed publicly as a good part about YARN.
> If it did complete it, we should document how to use it. Setting the following only yields:
> {code}
> <property>
> <name>yarn.resourcemanager.store.class</name>
> <value>org.apache.hadoop.yarn.server.resourcemanager.recovery.ZKStore</value>
> </property>
> <property>
> <name>yarn.resourcemanager.zookeeper-store.address</name>
> <value>test.vm:2181/yarn-recovery-store</value>
> </property>

> This JIRA is hence filed to track the addition/completion of recovery via ZK.
