Connect to SolrCloud using proxy in SolrJ

[Preeti Bhat <pr...@shoregrp.com>]

Hi All,

I am trying to connect to the Solrcloud using the zookeeper host string in my java application(CloudSolrClient). I am able to connect to the solrcloud when there are no proxy settings needed, but when trying to connect to the code using proxy settings, I am getting the below error.


1)      Without Proxy

System.setProperty("javax.net.ssl.keyStore", keyStore);

System.setProperty("javax.net.ssl.keyStorePassword", keyStorePsswd);

System.setProperty("javax.net.ssl.trustStore", trustStore);

System.setProperty("javax.net.ssl.trustStorePassword", trustStorePsswd);


HttpClientBuilder builder = HttpClientBuilder.create();
       builder.useSystemProperties();
       CloseableHttpClient httpclient = builder.build();
cloud_client = new CloudSolrClient(zkHost, httpclient);
@SuppressWarnings("rawtypes")
SolrRequest req = new QueryRequest();
req.setBasicAuthCredentials(UserName, Password);
       cloud_client.request(req, collectionName);

cloud_client.setDefaultCollection(collectionName);

2)      With Proxy code

System.setProperty("javax.net.ssl.keyStore", keyStore);

System.setProperty("javax.net.ssl.keyStorePassword", keyStorePsswd);

System.setProperty("javax.net.ssl.trustStore", trustStore);

System.setProperty("javax.net.ssl.trustStorePassword", trustStorePsswd);
System.setProperty("http.proxyHost", ProxyHost);
System.setProperty("http.proxyPort", ProxyPort);
HttpHost proxy = new HttpHost(ProxyHost, Integer.parseInt(ProxyPort));
RequestConfig defaultRequestConfig = RequestConfig.custom()
                                         .setProxy(new HttpHost(ProxyHost, Integer.parseInt(ProxyPort))).build();

HttpGet httpget = new HttpGet();
httpget.setConfig(defaultRequestConfig);

HttpClientBuilder builder = HttpClientBuilder.create();
builder.useSystemProperties();
CloseableHttpClient httpclient = builder.build();
httpclient.execute(proxy, httpget);
cloud_client = new CloudSolrClient(zkHost, httpclient);
@SuppressWarnings("rawtypes")
SolrRequest req = new QueryRequest();
req.setBasicAuthCredentials(UserName, Password);
cloud_client.request(req, collectionName);
cloud_client.setDefaultCollection(collectionName);


Please note that the Zookeepers are already whitelisted in the proxy under TCP protocol & SOLR servers are under https protocol.
Could someone please advise on this??

Thanks and Regards,
