> 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.
