Hi,
I have an issue when using http2 solr client with SOLR (v9.0.0 and 9.2.0)
cluster s configured with basic authentication.
Legacy solr cluster client is working fine.
Client creation code snippet:
CloudHttp2SolrClient.Builder builder = new
CloudHttp2SolrClient.Builder(solrUrls);
Http2SolrClient.Builder http2ClientBuilder = new Http2SolrClient.Builder();
http2ClientBuilder.withBasicAuthCredentials("user", "password");
builder = builder.withHttpClient(http2ClientBuilder.build());
SolrClient solrClient = builder.build();
Is it correct way to create http2 solr client?
Error thrown when initiating connection to solr cluster:
Caused by:
org.apache.solr.client.solrj.impl.BaseHttpSolrClient$RemoteSolrException: Error

Here is my findings:
org.apache.solr.client.solrj.impl.BaseHttpClusterStateProvider method void
init(List<String> solrUrls)
creates initialClient to get live nodes list:
public abstract class BaseHttpClusterStateProvider implements
ClusterStateProvider {
public void init(List<String> solrUrls) throws Exception {
for (String solrUrl : solrUrls) {
urlScheme = solrUrl.startsWith("https") ? "https" : "http";
try (SolrClient initialClient = getSolrClient(solrUrl)) {
this.liveNodes = fetchLiveNodes(initialClient);
org.apache.solr.client.solrj.impl.Http2ClusterStateProvider class method
getSolrClient rmethod returnes new instance of Http2SolrClient with
basicAuthAuthorizationStr = null while this.httpClient instance has not null
value basicAuthAuthorizationStr:
public class Http2ClusterStateProvider extends BaseHttpClusterStateProvider {
@Override
protected SolrClient getSolrClient(String baseUrl) {
return new
Http2SolrClient.Builder(baseUrl).withHttpClient(httpClient).build();
}
}
Http2SolrClient.Builder class build() method ignores basicAuthAuthorizationStr
fiekd value provided in httpClient instance in withHttpClient() method - basic
authentication string taken from new Http2SolrClient.Builder(baseUrl). builder
instance with blank credentials.
As result, initialClient instance has null basic credentials string and
connection to solr cluster fails (401 error).
Kind regards.
