Junping Du updated YARN-1000:
-----------------------------
Description:
There are some configurations for feature of dynamic resource configuration:
1. enable or not: if enable, then setting node resource in runtime through
CLI/REST/JMX can be successful, else exceptions of "function not supported"
will be thrown out. In future, we may support to enable this feature in partial
nodes which has resource flexibility (like virtual nodes).
2. dynamic resource setting is persistent or not: it depends on users' scenario
to see if the life cycle of setting in runtime should be kept after NM is down
and restart.
> Dynamic resource configuration feature can be configured to enable or disable
> and persistent on setting or not
