Subject [jira] [Commented] (YARN-1482) WebApplicationProxy should be always-on w.r.t HA even if it is embedded in the RM
Date Wed, 18 Dec 2013 23:11:08 GMT

    [ https://issues.apache.org/jira/browse/YARN-1482?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13852276#comment-13852276
] 

Xuan Gong commented on YARN-1482:
---------------------------------

as I describe on previous comment, the webapoproxy will keep looping if there is no active
rm. It will not keep doing it forever. Either it will find the active rm or it will crash
because of timeout.

About how long it will keep looping until the timeout happens is based on configurations that
we set up for failover (such as max-attempts, etc).

> This way, even if an RM goes to standby mode, we can affect a redirect to the active.
And more importantly, users will not suddenly see all their links stop working.
