org.apache.hadoop.yarn.api.records.NodeHealthStatus
NodeHealthStatus is a summary of the health status of the node.

It includes information such as:
- An indicator of whether the node is healthy, as determined by the health-check script.
- The previous time at which the health status was reported.
- A diagnostic report on the health status.
