Subject [jira] [Commented] (HADOOP-7532) Hadoop web UI 2.0
Date Fri, 19 Aug 2011 16:48:27 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7532?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13087795#comment-13087795

Luke Lu commented on HADOOP-7532:
---------------------------------

bq. Hamlet does have some unique capabilities, but it need not be hadoop-specific, and will
certainly become a maintenance headache later.

Hamlet is a light-weight pure java framework that's much smaller in code base than JSP itself.
IMO, the webapps created with Hamlet is much more maintainable than any existing web framework
because of Java/IDE/refactor friendliness.

bq. But I think the approach described by Robert Evans makes the most sense.

Except it doesn't really work in the context of MRv2. See my reply to Bobby in MAPREDUCE-2858
for details.

> 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.
