Description

Scanning the code, the only JSON-marshalled classes that declare their json property fields are the Agent ones ... most of which match their field names completely.

some are different, e.g in org.apache.slider.server.appmaster.web.rest.agent.HostInfo:

  @JsonProperty("uptime_hours")
  public long getUptimeHours() {
    return this.uptime_hours;
  }

  @JsonProperty("uptime_hours")
  public void setUpTimeHours(long uptime_hours) {
    this.uptime_hours = uptime_hours;
  }

  @JsonProperty("uptime_days")
  public long getUpTimeDays() {
    return this.uptime_days;
  }

  @JsonProperty("uptime_days")
  public void setUpTimeDays(long 

This may work for the agent POSTing data to the AM, as it is not Jersey itself publishing it —but if the AM did ever try to serve the same data up on its REST endpoints, the fields would not be marshalled correctly.
