Solrj-collection creation
Hi
I want to connect to solrCloud server from java program using
zookeeperHost variable. I know that data can be indexed and searched from a
collection using java program. but Can i able to create a collection
initially from java program?
My problem is that i cannot access solr web page, i'm getting an error like
"defected tokens detected". So, i wanted to connect to solr using solrj API.
For that I need to create a collection initially.Got struck here.
Anyone can help me.
Thanks in advance

Since you're using SolrJ anyway just use the
CollectionsAdminRequest. You can see
examples of it's use in the test cases, take a look
at CollectionsApiSolrJTests..
Best,
Erick

Generally, creating a collection may also include uploading a zookeeper configuration:
import org.apache.solr.common.cloud.SolrZkClient;
import org.apache.solr.common.cloud.ZkConfigManager;
import org.apache.solr.common.cloud.ZkStateReader;
/* ... much later ... */
SolrZkClient zkClient = something.getZkClient();
ZkConfigManager configManager = new ZkConfigManager(zkClient);
String confName = something.getConfigName();
configManager.uploadConfigDir(something.getPath(), confName);
Creating the collection looks like this:
import org.apache.solr.client.solrj.SolrClient;
import org.apache.solr.client.solrj.SolrServerException;
import org.apache.solr.client.solrj.request.CollectionAdminRequest;
import org.apache.solr.client.solrj.response.CollectionAdminResponse;
/* ... later ... */
CollectionAdminResponse response = new CollectionAdminResponse();
CollectionAdminRequest.Create request = new CollectionAdminRequest.Create();
request.setConfigName(something.getConfigName());
request.setCollectionName(collectionName);
request.setNumShards(1); // TODO: edit
request.setReplicationFactor(1); // TODO: edit
response.setResponse(client.request(request));

Yes. Use the CloudSolrClient object in the SolrJ API. It accepts a zkHost string.
https://cwiki.apache.org/confluence/display/solr/Using+SolrJ
I'm not sure exactly how to do the collection create, but it will probably involve this object:

This does not sound like an error generated by Solr. It must be coming from some other aspect of your environment. Can you get a screenshot or log entry showing the problem, place it on the Internet somewhere, and provide a link?
Thanks,
