>             Project: Ignite
>          Issue Type: Improvement
>            Reporter: Alexey Kuznetsov

>             Fix For: 2.2

>
> RestExecutor.sendRequest() contain following code:
> {code}
> ....
>         try (Response resp = httpClient.newCall(reqBuilder.build()).execute()) {
>             String content = resp.body().string();
>             if (resp.isSuccessful()) {
>                 JsonNode node = mapper.readTree(content);
> .... 
> {code}
> Problems: 
> # String content = resp.body().string(); >> Generate not needed String.
> # JsonNode node = mapper.readTree(content);  >> Generates a big tree of JsonNodes
>  
> Could be fixed like:
> RestResponseHolder res = MAPPER.readValue(resp.body().byteStream(), RestResponseHolder.class); 
> Where for RestResponseHolder should also created optimized RestResponseHolderDeserializer that will extract response as String without building tree of JsonNodes.
