The NodeManager's view
The NodeManager service in YARN updates its resource capabilities to the ResourceManager and tracks the execution of containers running on the node.
Other than the health of a node, the NodeManager service is responsible for the following:
- Execution of an application and its associated containers
- Provide localized resources for the execution of containers related to applications
- Manage logs of different applications
The NodeManager service has its own view for the following:

- Localized resource: This involves the files required for the container's execution
