Subject [jira] [Commented] (MAPREDUCE-4720) Browser thinks History Server main page JS is taking too long
Date Tue, 06 Nov 2012 19:30:12 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4720?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13491743#comment-13491743

Ravi Prakash commented on MAPREDUCE-4720:
-----------------------------------------

Thanks for the prompt reply Luke! The above curl was from a remote JHS. The 11 second time
was from a dev-box local psuedo-distributed cluster. I am wondering if there are some DataTables
options we are using which is making it slower? For instance, in the test file I created,
I hadn't made any of the fields searchable.

> 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.
