[jira] [Created] (NUTCH-2597) NPE in updatehostdb

JIRA jira@apache.org
Jurian Broertjes created NUTCH-2597:
---------------------------------------

             Summary: NPE in updatehostdb
                 Key: NUTCH-2597
                 URL: https://issues.apache.org/jira/browse/NUTCH-2597
             Project: Nutch
          Issue Type: Bug
          Components: hostdb
    Affects Versions: 1.15
            Reporter: Jurian Broertjes


I get an NPE on updatehostdb. I start with a clean crawlDB & hostDB. After an inject, I do an updatehostdb with -checkAll and get the following stacktrace:

2018-06-13 10:45:21,958 WARN hostdb.ResolverThread - java.lang.NullPointerException

Is this related to NUTCH-2375?

If further testing is needed, please let me know!
