<description>The class to use as the persistent store.
If org.apache.hadoop.yarn.server.resourcemanager.recovery.ZKRMStateStore
is used, the store is implicitly fenced; meaning a single ResourceManager

implicit fencing, along with setting up appropriate ACLs is discussed
under yarn.resourcemanager.zk-state-store.root-node.acl.

the applications remembered in RM memory.
Any values larger than ${yarn.resourcemanager.max-completed-applications} will
be reset to ${yarn.resourcemanager.max-completed-applications}.
Note that this value impacts the RM recovery performance.Typically,
a smaller value indicates better performance on RM recovery.

<description>ACL's to be used for ZooKeeper znodes.</description>

<value>world:anyone:rwcda</value>
</property>
<property>
<description>
ACLs to be used for the root znode when using ZKRMStateStore in a HA
scenario for fencing.
ZKRMStateStore supports implicit fencing to allow a single
ResourceManager write-access to the store. For fencing, the
ResourceManagers in the cluster share read-write-admin privileges on the
root node, but the Active ResourceManager claims exclusive create-delete
permissions.
By default, when this property is not set, we use the ACLs from
yarn.resourcemanager.zk-acl for shared admin access and
rm-address:random-number for username-based exclusive create-delete
access.
This property allows users to set ACLs of their choice instead of using
the default mechanism. For fencing to work, the ACLs should be
carefully set differently on each ResourceManger such that all the
ResourceManagers have shared admin access and the Active ResourceManger
takes over (exclusively) the create-delete access.
</description>

</property>
<property>
<description>
Specify the auths to be used for the ACL's specified in both the

the ZK CLI).

<description>If true, ResourceManager will have proxy-user privileges.
Use case: In a secure cluster, YARN requires the user hdfs delegation-tokens to
do localization and log-aggregation on behalf of the user. If this is set to true,
ResourceManager is able to request new hdfs delegation tokens on behalf of
the user. This is needed by long-running-service, because the hdfs tokens
will eventually expire and YARN requires new valid tokens to do localization
and log-aggregation. Note that to enable this use case, the corresponding
HDFS NameNode has to configure ResourceManager as the proxy-user so that
ResourceManager can itself ask for new tokens on behalf of the user when
tokens are past their max-life-time.</description>

Number of seconds after an application finishes before the nodemanager's
DeletionService will delete the application's localized file directory
and log directory.
To diagnose Yarn application problems, set this property's value large
enough (for example, to 600 = 10 minutes) to permit examination of these
directories. After changing the property's value, you must restart the
nodemanager in order for it to have an effect.
The roots of Yarn applications' work directories is configurable with
the yarn.nodemanager.local-dirs property (see below), and the roots
of the Yarn applications' log directories is configurable with the
yarn.nodemanager.log-dirs property (see also below).

<description>It limits the maximum number of files which will be localized

will be created and new files will be localized in them. If it is set to
a value less than or equal to 36 [which are sub-directories (0-9 and then
a-z)] then NodeManager will fail to start. For example; [for public
cache] if this is configured with a value of 40 ( 4 files +
36 sub-directories) and the local-dir is "/tmp/local-dir1" then it will
allow 4 files to be created directly inside "/tmp/local-dir1/filecache".
For files that are localized further it will create a sub-directory "0"
inside "/tmp/local-dir1/filecache" and will localize files inside it
until it becomes full. If a file is removed from a sub-directory that
is marked full, then that sub-directory will be used back again to
localize files.

Maximum number of proxy connections to cache for node managers. If set
to a value greater than zero then the cache is enabled and the NMClient
and MRAppMaster will cache the specified number of node manager proxies.
There will be at max one proxy per node manager. Ex. configuring it to a
value of 5 will make sure that client will at max have 5 proxies cached
with 5 different node managers. These connections for these proxies will
be timed out if idle for more than the system wide idle timeout period.
Note that this could cause issues on large clusters as many connections
could linger simultaneously and lead to a large number of connection
threads. The token used for authentication will be used only at
connection creation time. If a new token is received then the earlier
connection should be closed in order to use the new token. This and
(yarn.client.nodemanager-client-async.thread-pool-max-size) are related
and should be in sync (no need for them to be equal).
If the value of this property is zero then the connection cache is
disabled and connections will use a zero idle timeout to prevent too
many connection threads on large clusters.
