> Solr processors failing to authenticate against Kerberized Solr
> ---------------------------------------------------------------
>
> Key: NIFI-5148
> URL: https://issues.apache.org/jira/browse/NIFI-5148
> Project: Apache NiFi
> Issue Type: Bug
> Affects Versions: 1.6.0
> Reporter: Bryan Bende
> Assignee: Bryan Bende
> Priority: Major
> Fix For: 1.7.0
>
>
> It appears that with the new default value of "useSubjectCredsOnly=true" in
> NiFi's bootstrap.conf that this can cause an issue for the Solr processors
> when talking to a kerberized Solr.
> The SolrJ client code that we are using specifically calls this out as being
> problematic:
> [https://github.com/apache/lucene-solr/blob/branch_6x/solr/solrj/src/java/org/apache/solr/client/solrj/impl/Krb5HttpClientConfigurer.java#L75-L88]
> We should refactor the kerberos approach in the Solr processors to resolve
> this issue and make general improvements. We should be performing a JAAS
> login and wrapping calls in Subject.doAs, and we should try and move away
> from the system level JAAS property and leverage the new keytab controller
> service.
