[jira] [Updated] (YARN-4515) [YARN-3368] Support hosting web UI framework inside YARN RM

["Sunil G (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/YARN-4515?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Sunil G updated YARN-4515:
--------------------------
    Attachment: 0001-YARN-4515.patch

Attaching an updated patch with changes from UI end also

Things handled:
- All pages can be accessed now via a deployed UI2 under httpserver2.
- Configuration supported is added to choose web port.
- Used "#" as prefix for all hyper references. For external URLs, this is needed. For internal routes, used {{link-to}}. I could not use {{link-to}} for some more route redirection as it has more input params. I will try fix that also if possible.

Things to notice (or not handled in this patch)
- Maven support to package the compiled UI2 war and put it under $share/hadoop/yarn/rm. I will update this in next patch. Pls use steps mentioned by [~leftnoteasy] for now.
- When there are no apps/nodes available, few error message is shown under the table as a row. This will cause a warning. So i have not shown the whole table, and just shown a message. PLs suggest some other alternatives if you feel.

[~leftnoteasy]/[~varun_saxena]. pls help to check the same.

> Currently it can be only launched outside of YARN, we should make it runnable inside YARN for easier testing and we should have a configuration to enable/disable it.
