> Hi, We are using Apache Knox to guardrail our perimeter for our Hadoop Cluster. As part of this we are abstracting out many APIs and putting them behind Knox
> We had a requirement where we want to append some service specific headers in the API calls before Knox submits it to the service. Livy had a similar implementation but Livy created a whole new Dispatcher to do this
> We have different APIs and different set of headers for all of them. We are suggesting to enlarge scope of current ConfigurableDispatcher to also allow one more param:
>  
> <param>
>  <name>requestAppendHeaders</name>
>  <value>\{"a":"b"}</value>
>  </param>
>  
> If given above param, Knox while submitting the request to the service, will add these headers along with the request
