--------------------------------------
Summary: Injector to stop if job fails to avoid loss of CrawlDb
Key: NUTCH-2442
URL: https://issues.apache.org/jira/browse/NUTCH-2442
Project: Nutch
Issue Type: Bug
Components: injector
Affects Versions: 1.13
Reporter: Sebastian Nagel
Priority: Critical
Fix For: 1.14
Injector does not check whether the MapReduce job is successful. Even if the
job fails
- installs the CrawlDb
-- move current/ to old/
-- replace current/ with an empty or potentially incomplete version
- exits with code 0 so that scripts running the crawl workflow cannot detect
the failure -- if Injector is run a second time the CrawlDb is lost (both
current/ and old/ are empty or corrupted)
--
