Subject: Re: Regarding checksum error in hadoop in my
the test fails because nothing is generated, i.e. the tests detected a broken
Best is to test generator from the command-line whether they behave as
expected, e.g. (with a
$ bin/nutch generate path/to/crawldb path/to/segments/
Generator: segment: path/to/segments/20170811152636
Generator: finished at 2017-08-11 15:26:37, elapsed: 00:00:03
$ tree path/to/segments/
The folder crawl_generate is empty! Generator is complex with multiple steps
working in temporary
folders. Eventually, it's only the final copying which is broken. But I see no
other way as to debug
the fetch list generation to find out what the reason is.
I strongly recommend to test also all other tools from command-line. For the
bulk of them just run
a sample crawl via bin/crawl.
