 ### Recovering prevous active-RM's state
 
-With the [ResourceManger Restart](./ResourceManagerRestart.html) enabled, the RM being promoted
to an active state loads the RM internal state and continues to operate from where the previous
active left off as much as possible depending on the RM restart feature. A new attempt is
spawned for each managed application previously submitted to the RM. Applications can checkpoint
periodically to avoid losing any work. The state-store must be visible from the both of Active/Standby
RMs. Currently, there are two RMStateStore implementations for persistence - FileSystemRMStateStore
and ZKRMStateStore. The `ZKRMStateStore` implicitly allows write access to a single RM at
any point in time, and hence is the recommended store to use in an HA cluster. When using
the ZKRMStateStore, there is no need for a separate fencing mechanism to address a potential
split-brain situation where multiple RMs can potentially assume the Active role. When using
the ZKRMStateStore, it is advisable to NOT set the
  "`zookeeper.DigestAuthenticationProvider.superDigest`" property on the Zookeeper cluster
to ensure that the zookeeper admin does not have access to YARN application/user credential
information.

 ### Configurations
 
-Most of the failover functionality is tunable using various configuration properties. Following
is a list of required/important ones. yarn-default.xml carries a full-list of knobs. See [yarn-default.xml](../hadoop-yarn-common/yarn-default.xml)
for more information including default values. See the document for [ResourceManger Restart](./ResourceManagerRestart.html)
also for instructions on setting up the state-store.
