Hi all, for NUTCH-251:
I suppose that NUTCH-251 is relatively a significant issue by the votes.
Stafan has written a good plugin for the admin gui and i have updated it
to work with nutch-0.8, hadoop 0.4.
Some of the features in the patch is not appropriate for our use cases
and it requires hadoop changes, thus I am currently working on an
alternative implementation of the administration gui, which runs a
hadoop server( like JobTraker) to listen to submitted Jobs, an web Gui
to submit and track the jobs from the browser and a job runner.
The architechture details of the patch is as follows :
- An interface AdminJob which is an abstract class representing a Job
in nutch.
- various classes extending AdminJob. for ex FetchAdminJob, IndexAdminJob.
- A queue which sorts the jobs in priority order, by a modified a
topological sort(jobs can be dependent).
- an interface to submit Jobs
- a rpc server to listen to job submissions
- an extension point (basically same as the previous)
- a web server to serve plugin jsp's
upon the features will be
- submitting jobs from code, command line or web interface,
- tracking jobs from the command line or web interface
- scheduling jobs
I could send the code or details if anyone is interested in pretesting.
And i will appreciate any comments and suggestions on this. I am
planning to complete the patch and submit it to Jira ASAP.
