> 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.
