Review comment:
Prefer not to use too many temp variables. I think it can be simplified to:
```java
if (map.containsKey("hosts")) {
hosts = mapper.convertValue(map.get("hosts", new
TypeReference<List<String>>() { })).stream() ... ;
} else if (map.containsKey("coordinates")) {
hosts = mapper.convertValue(map.get("coordinates", new
TypeReference<Map<String, Integer>>() { })).stream() ... ;
}
