Description

A rewrite rule for Yarn UI v2 should look like this for Oozie UI:

    <rule dir="OUT" name="OOZIE/oozie/console-url" pattern="*://*:*/proxy/{application_id}">
        <rewrite template="{gateway.url}/yarnuiv2/redirect/#/yarn-app/{application_id}/attempts"/>
    </rule>

    <filter name="OOZIE/oozie/jobinfo">
        <content type="*/json">
            <apply path="$.actions..consoleUrl" rule="OOZIE/oozie/console-url" />
        </content>
    </filter> 

but it results:

https://externally_available_knox_domain_name:8443/gateway/cdp-proxy/yarnuiv2/redirect/#/yarn-app/{application_id}/attempts 

You can see that the rewrite process does not resolve the application_id variable. To be honest no variable is resolved placed after the hash mark. If I use any encoded form of the hash mark then the variables are resolved but when I "click" on the url I get:

 HTTP ERROR 404 Not Found
URI:	/redirect/%23/yarn-app/application_1632341699345_0003/attempts
STATUS:	404
MESSAGE:	Not Found
SERVLET:	org.eclipse.jetty.servlet.DefaultServlet-79c4f23b
