Chandana Mirashi commented on AMBARI-21325:
-------------------------------------------
Yes, Spark2 History UI changed some of the links and underlying structure from
previous versions of Spark. Hence had to create a new version in Knox to
support Spark2. Given that we already had customers on previous version, the
earlier version service definitions were not replaced to account for those
customers.If everyone moves to Spark 2 then 1.4 version will be obsolete.
> Ability to switch Quick Links to use Service URL through Knox or given proxy

> Knox has the ability to proxy Hadoop user interfaces URL. Having the ability
> to setup Quicklinks through Knox so instead of for example going to "Hbase
> Master UI" directly we can proxy through Knox for example:
> http://hdpjeff1.fyre.ibm.com:16010/master-status
> can be instead go through:
> https://hdpjeff1.fyre.ibm.com:8443/gateway/default/hbase/hbaseui/master-status
> Here https://hdpjeff1.fyre.ibm.com:8443/gateway is the Knox gateway URL.
> This will bring authentication to the UI access and would secure the UI
> access.
> Ideally this behavior can be set as secure going through proxy by default or
> it can be turn off to go directly by Ambari Admin.
> Changes added:
> 1. Add new json properties knox_url, knox_path, supports_knox
> a. knox_url: template to be used for urls that are proxied through Knox
> b. knox_path: Knox gateway path that will be added to the proxy url.
> c. supports_knox: whether link will be redirected through Knox
> 2. Add above json properties to quicklinks.json
> 3. Add HDFSUI & DATANODE,YARNUI & NODEUI, JOBHISTORYUI, HBASEUI, OOZIEUI,
> SPARKUI services to Knox topology template.
> 4. Automate protocol and port added to Knox topology file. Based on whether
> SSL is enabled for the services listed above, the port and protocol in
> params_linux.py will be updated.
> 5. Update quick_view_link_view.js so that when Knox is installed and
> support_knox is true, quicklink url follows knox url template specified in
> the quicklinks.json for the service/component.
