Subject [jira] Updated: (NUTCH-634) Patch - Nutch - Hadoop 0.17.0
Date Tue, 24 Jun 2008 19:26:45 GMT


Lincoln Ritter updated NUTCH-634:

    Attachment: hadoop-0.17.patch

My previous patch left out and
 This patch includes them.

However, I don't think these are long-term solutions.  Michael can clarify, but it seems that
this code is meant to deal with thinks like '_logs' directories in Hadoop.  What we really
need is some way to ask Hadoop whether the a directory or file is somehow 'special'.  I'm
not sure what the definition of 'special' is here though...

Michael suggested there was a way to do this and I will be looking into it as well, but it
would be nice if someone more familiar with Hadoop than I am could chime in to suggest a course
of action here.

> This is a patch so that Nutch can be used with Hadoop 0.17.0. The patch is located at
> The patch compiles and passes all current Nutch unit tests.
> I have tested that the crawler side of Nutch (i.e. inject, generate, fetch, parse, merge
w/crawldb) definetly works, but have not tested the lucene indexing part. It might work, but
it might not. 
> *NOTE* - the two main bugs that had to be overcome were not noticed by any of the unit
tests. The bugs only came up during actual testing. The bugs were:
> 1. Changes to the Hadoop Iterator
