Subject [jira] [Commented] (HADOOP-7532) Hadoop web UI 2.0
Date Thu, 18 Aug 2011 21:38:28 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7532?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13087315#comment-13087315

Eli Collins commented on HADOOP-7532:
-------------------------------------

Re-implementing templating engine feels out of scope to me as well. My main concern is not
about the quality of Hamlet - I assume it's good stuff - but that a Hadoop-only web framework
is not going to be actively advanced like other projects and so in a couple of years we'll
be on something that's pretty out of date and that only a small number of people know how
to change (like our RPC library and serialization framework).

Luke - have you considered making Hamlet into a separate project and having Hadoop consume
this project? I'd be less worried about the above if there was a community built around Hamlet.
The advantages of Hamlet you've outlined should make it useful to any project and therefore
would attract a community. Similarly, if MR is the only project willing to adopt Hamlet then
I wonder if it's a wise choice.

> People have expressed interests of bringing Hadoop web UI up to date with the lightweight
embedded web mvc framework used in MAPREDUCE-279 (cf. MAPREDUCE-2399). This is the umbrella
jira for UI improvement for 0.23+. Individual items like web framework refactor/move and the
unique challenge for MR2 webapp security will be filed separately.
> Thoughts/ideas on various improvement of Hadoop web UI are welcome here. Some of the
ideas will naturally become sub-issues.
