Ravi Prakash updated MAPREDUCE-4720:
------------------------------------
Attachment: MAPREDUCE-4720.patch
Thanks for that Luke! I *had* updated it in a separate branch and forgot to
include it in the patch. Here's the whole branch. I generated this patch using
git diff --binary --no-prefix --full-index . I have yet to figure out how to
apply this using patch.
Nathan had suggested me to use YSlow and fix the bad grade it gave. I put in a
few improvements:
1. Combined multiple Javascript files so that fewer HTTP connections are opened.
2. Static content is being sent with the "Expires" header set to an year from
when the request is made.
3. Datatables upgraded and deferred rendering.
Its taking about 8 seconds to render the 20000 fake jobs. An improvement from
11 seconds but still leaves something to be desired.
Questions:
1. Should I combine all the JS files? Or only the well known jquery, jquery-ui
and jquery-datatables libraries?
2. Should I version the static directory? I didn't feel the need because a
refresh on the client browser can be made to refetch the un-expired content
anyway.
3. Is there anything else we should be doing?

> 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.
