I started a Solrcloud by running the included example bin/solr -e cloud, and in that case, I managed to start up a three nodes Solr cloud and created a gettingstarted collection: 

http://localhost:8983/solr/admin/collections?action=CREATE&name=gettingstarted&numShards=3&replicationFactor=2&maxShardsPerNode=2&collection.configName=gettingstarted

I think it comes with a embedded zookeeper running on port 9983 because I saw this output when I started the cloud: 

...
Starting up Solr on port 7574 using command:
bin/solr start -cloud -p 7574 -s "example/cloud/node2/solr" -z localhost:9983
Waiting up to 30 seconds to see Solr running on port 7574 [/] 
...

However, when I tried to connect to the SolrCloud using SolrJ, it failed with the error message: 

Exception in thread "main" org.apache.solr.common.SolrException: Cannot connect to cluster at localhost:9983/solr: cluster not found/not ready

enter image description here

Can anyone help me understand what is going on here?

    For anyone wondering, the Zookeeper connection string should contain ALL zookeeper servers in your zookeeper cluster, separated by commas, SOME zookeeper configuration use a chroot or application root, this is when the ``/solr`` appears at the end of the query string. This would be needed when you have a chroot at ``/solr`` within Zookeeper. For most configurations this can be omitted. – Ben DeMott Mar 08 '17 at 22:13
  • @BenDeMott Maybe this should be an answer? – Gert Arnold Mar 30 '17 at 20:11

The code fails because you are trying to point the CloudSolrServer to a znode that does not exist. Your zkhost is not configured with a /solr chroot. The configs seem to be stored at the root node.

So change the line 

String zkHostString = "localhost:9983/solr";

to 

String zkHostString = "localhost:9983";

and your code should work.

It depends on your zkHost. If your zkHost contains /solr , then it should be localhost:2181/solr or localhost:9983/solr; Otherwise , localhost:yourport
