> When YARN responds with or accepts JSON, numbers & booleans are being represented
as strings which can cause parsing problems.
> Resource values look like 
> {
>   "application-id":"application_1404198295326_0001",
>   "maximum-resource-capability":
>    {
>       "memory":"8192",
>       "vCores":"32"
>    }
> }
> Instead of
> {
>   "application-id":"application_1404198295326_0001",
>   "maximum-resource-capability":
>    {
>       "memory":8192,
>       "vCores":32
>    }
> }
> When I POST to start a job, numeric values are represented as numbers:
>       "local-resources":
>       {
>         "entry":
>         [
>           {
>             "key":"AppMaster.jar",
>             "value":
>             {

>             }

> Similarly, Boolean values are also represented as strings:
> "keep-containers-across-application-attempts":"false"
> Instead of 
> "keep-containers-across-application-attempts":false
