Missing username and password properties from the solr connector configuration to authenticate with the solr.

Is that possible to authenticate with solr via connector config?

How to pass username n password within the connector config?

  • Have you tried including the `user:pass` combination in the URL as you'd do with a regular http url including username and password? (`http://username:password@host/..`) – MatsLindh Jun 25 '21 at 09:37
  • Yes I have Tried it but still getting same issue. – Rabeesh Jun 25 '21 at 11:04
  • According to the source it seems you can use `solr.username` and `solr.password` to provide authentication details. https://github.com/bkatwal/kafka-solr-sink-connector/blob/f0d022607f3d5419053bfb0c87a710fb37e00896/src/main/java/com/bkatwal/kafkaproject/SolrSinkConnectorConfig.java#L37 – MatsLindh Jun 25 '21 at 11:25
  • Yes I Have Checked it n it gives me error like Caused by: org.apache.solr.client.solrj.impl.HttpSolrClient$RemoteSolrException: Error from server at http://IP:PORT/solr: Expected mime type Error 401 require authentication

    HTTP ERROR 401 require authentication

    URI:/solr/FX_TRAN/update
    STATUS:401
    MESSAGE:require authentication
    SERVLET:default

Looks like solr.username and solr.password aren't actually used in the connector. The SolrClient is created with a default HttpSolrClient without any credentials in this source file in Github. But MatsLindh's point about embedding username and password in the URL is a good one and I'd have expected it to work.

There's a relevant thread here:

Solr6.3.0 SolrJ API for Basic Authentication

I haven't vetted the last answer in the thread, which doesn't really address the original topic in that post, but it is a concise example of creating a SolrClient with authentication. The SolrClient needs to wrap an underlying HttpClient that provides the basic auth, and the Kafka Solr sink connector isn't doing that.
