Subject [jira] [Commented] (MAPREDUCE-4720) Browser thinks History Server main page JS is taking too long
Date Tue, 06 Nov 2012 19:14:12 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4720?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13491721#comment-13491721
] 

Luke Lu commented on MAPREDUCE-4720:
------------------------------------

There is no need to combine the js files, as these requests should be a fraction of the that
8 seconds and mostly cached. Can you post the entire profile of the request? I recall that
you said on YARN-151, 20k rows only takes 1 second to render with deferred rendering.

BTW, git apply <patch> would work.

> The main History Server page with the default settings of 20,000 jobs can cause browsers
to think that the JS on the page is stuck and ask you if you want to kill it. This is a big
usability problem.
