After examining the Nutch 1.2 CrawlDbConverter:

And running it:

Both against:
* crawldb
* whole crawl dir
* segments
etc., it produces no output and I can't seem to figure out how to use it. So,
rather than invest more time here, I am going to suggest that if in 48 hours, I
don't hear objections, I'm going to delete the testresources/testcrawl since
it's not referenced anywhere in the code.

> Key: NUTCH-1844
> URL: https://issues.apache.org/jira/browse/NUTCH-1844
> Project: Nutch
> Issue Type: Bug
> Components: test
> Reporter: Chris A. Mattmann
> Assignee: Chris A. Mattmann
> Fix For: 1.10
>
>
> While working on NUTCH-1526 in Review Board
> https://reviews.apache.org/r/9119/ [~lewismc] tried to test out the
> ./bin/nutch dump tool on src/testresources/testcrawl and found that it failed
> due to an old o.a.h.io.UTF8 key type (instead of the o.a.h.io.Text) type.
> I looked into this - how were Nutch tests passing using this old code? I
> found that Andrzej a long time ago wrote a tool to update the index from the
> old UFT8 key format to Text - I also found that *no where in the Nutch code*
> is the testcrawl referenced.
> My suggestion:
> * we remove the testcrawl (it's not used)
> * if we don't remove it, we at least run Andrzej's tool on it and then
> upgrade it to use o.a.h.io.Text keys.
> I'll take care of this.
