Subject Re: Solr Output Connector: SolrCloud with Kerberos / Zookeeper with Kerberos
Date Tue, 17 Dec 2019 06:22:25 GMT
I agree.
The delegation part is not relevant for me. I also do not believe it makes sense at the ETL
 I think still we need add the one line of code that allows to use Kerberos (second line in
the example).

 So if you can point me at the SolrJ documentation for this configuration I can perhaps review
it and give you my opinion as to the difficulty involved.
