https://github.com/apache/flink/pull/5573
Hi @aljoscha and @tillrohrmann I have tried to put `Map<String,
SerializedValue<Object>>` into `JobAccumulatorsInfo` with two ways :
* a `@JsonProperty`
* marked with `@JsonIgnore` and provide getter and setter
and the two ways both failed with different reason:
* first way : throw a exception : `SerializedValue` no suitable constructor;
* second way : the setted object will be ignore by
`HandlerUtils#sendResponse`
In `JobAccumulatorsHandler#handleRequest` I can not return `Map<String,
SerializedValue<Object>>` directly, because this method's result type must
extends `ResponseBody`.
