Description

The NodeReport returned by getClusterNodes or given to AMs in heartbeat responses includes both a NodeState (enum) and a NodeHealthStatus (object). As UNHEALTHY is already NodeState, a separate NodeHealthStatus doesn't seem necessary. I propose eliminating NodeHealthStatus#getIsNodeHealthy and moving its two other methods, getHealthReport and getLastHealthReportTime, into NodeReport.
