> We are trying to use Hadoop authentication with Kerberos in Solr 8.4.1 and
> encountered a problem. We’re using a Hadoop 3.1.1 based fork. We are using
> JDK8 so we fall back to HTTP/1.1 but also tested with JDK11 (HTTP/2) and we
> got the same error.
> We have already added a few upstream changes which are not yet committed
> (SOLR-9840) or committed only later (SOLR-11554).
> The important part of our security.json file is:
> {noformat}
> "authentication": {
> "class":
> "org.apache.solr.security.ConfigurableInternodeAuthHadoopPlugin",
> "sysPropPrefix": "solr.authentication.",
> "type": "multi-scheme",
> "clientBuilderFactory":
> "org.apache.solr.client.solrj.impl.Krb5HttpClientBuilder",
> ...
> {noformat}
> When we try to add a document using curl we receive 401 error:
> {noformat}
> curl -k --negotiate -u :
> '[https://quasar-mdzaga-1.vpc.cloudera.com:8985/solr/test2/update]' -H
> 'Content-type:application/json' -d ' [ \{"id":"book3", "title":"book3title",
> "author":"author"} ]'\{ "responseHeader":{ "rf":2147483647,
> "status":401, "QTime":18}, "error":{ "metadata":[
> "error-class","org.apache.solr.update.processor.DistributedUpdateProcessor$DistributedUpdatesAsyncException",

> "Code":401}}
> {noformat}
> We have debugged the problem and found that curl can send the information to
> the node, and the internode TOLEADER request fails, because we don’t answer
> to the 401 challenge that is part of the SPNEGO mechanism:
