Reg: Nutch Admin GUI

[Prafulla <pr...@gmail.com>]

Hi,

We are looking to develop an Admin GUI for the Nutch Project. We came across
this page http://wiki.apache.org/nutch/NutchAdministrationUserInterface
but most of the links for download and screen shots given there are
outdated. Can we please know the current status of the work in this area and
whether there are any working plugins that can be used to extend the GUI for
Nutch-0.9.

Regards,
Prafulla
Aditya

AFAIK there was no progress on this issue. The patches that implemented 
GUI required changes in Hadoop, and even then it was only possible to 
run the GUI servlet within the same JVM as the JobTracker.

In my opinion, what is needed to move forward with this issue is the 
following:

* work on extending JobSubmissionProtocol in Hadoop to allow for a 
greater control and status reporting from JobTracker (this would address 
the bulk of Hadoop patches in the original patch-set)

* implement a "segment manager" tool to keep track of segments and their 
processing status. This is mostly implemented in the original patch. 
This would require that various Nutch tools have a greater consistency 
in the way they process segments and databases, and probably needs more 
status reporting between the tools.
