Subject [jira] [Commented] (HADOOP-7827) jsp pages missing DOCTYPE

Ivan Mitic commented on HADOOP-7827:
------------------------------------

Hi folks,

I spent some time investigating the IE9 render issues on branch-1 (and regression mentioned
in HADOOP-7867). If I see things correctly, the cause of the regression is browsers failing
to load the css file. Now that we changed the browser mode to HTML5, it fails to load the
css file if the returned server content type does not match the expected value (in this case
text/css).

The problem for this seems to be in HttpServer.java, where {{QuotingInputFilter#doFilter}}
always sets the context type to {{text/html}}. This was fixed with HADOOP-6496, so the missing
piece is to backport this changelist. Will attach a patch for the backport.

Let me know if I should also rebase the changes to the latest trunk/branch-1.1, I'll be happy
to do that.

Hope this helps

> The various jsp pages in the UI are all missing a DOCTYPE declaration.  This causes the
pages to render incorrectly on some browsers, such as IE9.  Every UI page should have a valid
tag, such as <!DOCTYPE HTML>, as their first line.  There are 31 files that need to
be changed, all in the core\src\webapps tree.
