> Currently with Knox 1.5.0 on a cluster with both Spark History Server and MR 
> JobHistory Server running the stdout and stderr links target the MR 
> JobHistory Server Web UI directly. For us this breaks them because we require 
> Knox fronted proxy access to the MR JobHistory Server on our production 
> cluster.

> A similar issue was raised in:
>  - KNOX-1744
>  - KNOX-1988
> However in this case the links are going to the MR JobHistory Server not YARN 
> RM so the targets are different and the previous rewrites do not apply.
