Subject [jira] [Commented] (YARN-7711) YARN UI2 should redirect into Active RM in HA
Date Mon, 08 Jan 2018 08:25:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-7711?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16315860#comment-16315860

Sunil G commented on YARN-7711:

Thanks [~rohithsharma] [~naganarasimha_gr@apache.org]

UI2 is based on js framework (ember). We download statics (such as images, js files, icons)
from the server which is hosting (Currently both RM has this). Once we have statics, page
will be rendered and then server invocation will done to fetch data (This will be done only
from ACTIVE RM). Hence after switching, basic static may b served from standby RM, however
data is fetched only from Active RM. In contrast to old UI where it is a server side impl,
new UI is end to end client side. So it helps to overcome this redirects etc.

> When UI2 is enabled in HA mode, if REST query goes into stand by RM, then it is not redirecting
into active RM. 
> It should redirect into Active RM as old UI redirect into active!
