Subject [jira] [Commented] (HDFS-4670) Style Hadoop HDFS web ui's with Twitter's bootstrap.
Date Tue, 09 Apr 2013 16:52:16 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4670?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13626811#comment-13626811

Chris Nauroth commented on HDFS-4670:
-------------------------------------

I took the new UI for a test drive.  It looks great!  A couple of higher-level questions:

# Is there a specific set of browsers/versions that we intend to support?  The old UI was
so basic that pretty much any browser could handle it to some degree.  Bootstrap itself claims
wide cross-browser support all the way back to IE7, though I don't know if that's only for
a specific subset of its functionality.  I did some non-exhaustive testing with Chrome, Firefox
and Safari on Mac, and IE8 on Windows, and they all looked fine.  I don't have access to anything
older than IE8.  I haven't tried any mobile browsers.
# Does it degrade gracefully if Javascript is disabled?  I have seen deployments that place
the Hadoop cluster behind a firewall with users only having access to the UI through a browser
that by policy disables Javascript.
# Considering that it's common to screen-scrape the old pages, do we need to mark this change
backwards-incompatible, or at least put a warning in the release notes?

I haven't checked all of the code, but I did spot this typo:

{code}
      "     <td>Compilcation Information</td>" +
{code}

Thanks, Elliott!

> A users' first experience of Apache Hadoop is often looking at the web ui.  This should
give the user confidence that the project is usable and relatively current.
