Nicolas Colomer created KNOX-1743:
-------------------------------------
Summary: [Yarn UI Service] "Tracking UI" History link is broken
Key: KNOX-1743
URL: https://issues.apache.org/jira/browse/KNOX-1743
Project: Apache Knox
Issue Type: Bug
Affects Versions: 1.2.0
Reporter: Nicolas Colomer
Attachments: image-2019-01-22-12-58-43-987.png
The "Tracking UI" History link from the Yarn UI Service points to
{noformat}
https://knox/gateway/cluster/yarn/proxy/{application id}{noformat}
but clicking the link leads to an HTTP 404 error.

I traced the redirections (spaghetti) while simulating a click on the same link
from a non-proxified Yarn UI. Here are the curl debug logs:
{code:java}

{code}
I guess adding some voodoo in the Knox yarnui's
[rewrite.xml|https://github.com/apache/knox/blob/master/gateway-service-definitions/src/main/resources/services/yarnui/2.7.0/rewrite.xml]
file might be enough to fix this.
