Can we used CloudSolrServer for searching data
I am using Solrcloud with zookeeper setup. but when I try to make query using following code snippet I get exception code: CloudSolrServer server = new CloudSolrServer(localhost:2181); server.setDefaultCollection(gettingstarted); server.connect(); SolrQuery query = new SolrQuery(); query.setQuery(q); QueryResponse rsp; rsp = server.query(query); Exception: Exception in thread main org.apache.solr.common.SolrException: Collection not found: gettingstarted at org.apache.solr.client.solrj.impl.CloudSolrServer.getCollectionList(CloudSolrServer.java:679) at org.apache.solr.client.solrj.impl.CloudSolrServer.request(CloudSolrServer.java:562) at org.apache.solr.client.solrj.request.QueryRequest.process(QueryRequest.java:91) at org.apache.solr.client.solrj.SolrServer.query(SolrServer.java:301) at Test.testSelectQueryCloudServer(Test.java:243) at Test.main(Test.java:357) I’ve verified the collection exists on zookeeper using zkCli and I can query using solr admin Sent from Windows Mail
Re: Can we used CloudSolrServer for searching data
Thanks for your reply. I am using Solrcloud with zookeeper setup. And using CloudSolrServer for both indexing and searching. As per my understanding CloudSolrserver by default using LBHttpSolrServer. And CloudSolrServer connect to Zookeeper and passing all the running server node to LBHttpSolrServer. Thanks for you guys once again for your reply. -- View this message in context: http://lucene.472066.n3.nabble.com/Can-we-used-CloudSolrServer-for-searching-data-tp4086766p4089475.html Sent from the Solr - User mailing list archive at Nabble.com.
Re: Can we used CloudSolrServer for searching data
Shalin is right. If you read the documentation for CloudSolrServer you will see that: *SolrJ client class to communicate with SolrCloud. Instances of this class communicate with Zookeeper to discover Solr endpoints for SolrCloud collections, and then use the LBHttpSolrServer to issue requests.* * * It uses *LBHttpSolrServer *for communication and that is what are you looking for. Here is explanation of constructing it: SolrServer lbHttpSolrServer = new LBHttpSolrServer(http://host1:8080/solr/,http://host2:8080/solr,http://host2:8080/solr;); //or if you wish to pass the HttpClient do as follows httpClient httpClient = new HttpClient(); SolrServer lbHttpSolrServer = new LBHttpSolrServer(httpClient,http://host1:8080/solr/,http://host2:8080/solr,http://host2:8080/solr;); Than you can use it as a *SolrServer*. 2013/9/3 Shalin Shekhar Mangar shalinman...@gmail.com CloudSolrServer can only be used if you are actually using SolrCloud (i.e. a ZooKeeper aware setup). If you only have a multi-core setup, then you can use LBHttpSolrServer.
