---------------------------------
Summary: 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
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.
