Work Description: deepashreeraghu commented on pull request #204: KNOX-2135-YARN-RM-Logs sub-links fix
URL: https://github.com/apache/knox/pull/204
## What changes were proposed in this pull request?
The logs sublinks under the YARN's RM log links are broken. This PR includes changes in the rewrite file and service file to update the body of the logs link so that the sublinks are rewritten appropriately.
## How was this patch tested?
This patch was tested by creating a hadoop cluster and rewriting links using the knox gateway.
The logs sublinks that were failing before patch are now working.
Attaching a screenshot below.

In the screenshot, the link being hovered on shows the properly rewritten link in the bottom.
