<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>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.
