Junping Du updated YARN-313:
----------------------------
Release Note:
After this patch, the feature to support NM resource dynamically configuration
is completed, so that user can configure NM with new resource without bring NM
down or decommissioned.
Two CLIs are provided to support update resources on individual node or a batch
of nodes:
1. Update resource on single node: yarn rmadmin -updateNodeResource [NodeID]
[MemSize] [vCores]
2. Update resource on a batch of nodes: yarn rmadmin -refreshNodesResources,
that reflect nodes' resource configuration defined in dynamic-resources.xml
which is loaded by RM dynamically (like capacity-scheduler.xml or
fair-scheduler.xml).
The first version of configuration format is:
<configuration>
<property>
<name>yarn.resource.dynamic.nodes</name>
<value>h1:1234</value>
</property>
<property>
<name>yarn.resource.dynamic.h1:1234.vcores</name>
<value>16</value>
</property>
<property>
<name>yarn.resource.dynamic.h1:1234.memory</name>
<value>1024</value>
</property>
</configuration>

Since this patch, we are providing CLI to support NM resource dynamically
configuration that user can configure NM with new resource without bring NM
down or decommissioned.
Two CLIs are provided to support update resources on individual node or a batch
of nodes:

[MemSize] [vCores]
2. Update resource on a batch of nodes: yarn rmadmin -refreshNodesResources,
that reflect nodes' resource configuration defined in dynamic-resources.xml,
the format of configuration is get optimized in YARN-4160.
