> indexer fails if linkdb is missing
> ----------------------------------
>
> Key: NUTCH-2041
> URL: https://issues.apache.org/jira/browse/NUTCH-2041
> Project: Nutch
> Issue Type: Bug
> Components: indexer, linkdb
> Affects Versions: 1.10
> Reporter: Sebastian Nagel
> Fix For: 1.11

> If the linkdb is missing the indexer fails with
> {noformat}
> 2015-06-17 12:52:10,621 ERROR
> ...cause:org.apache.hadoop.mapred.InvalidInputException: Input path does not
> exist: .../linkdb/current
> {noformat}
> If both db.ignore.internal.links and db.ignore.external.links there will be
> no LinkDb even if "invertlinks" is run (as consequence of NUTCH-1913). The
> script "bin/crawl" does not know about the values of these two properties and
> calls indexer with "-linkdb .../linkdb" which will then fail.
> Since "bin/crawl" is agnostic to properties defined in nutch-site.xml we
> solution similar to NUTCH-1854: make the tool/job more tolerant and log a
> warning instead of raising an error.
