Not sure about the documentation but:
The CloudSolrClient uses a connection to zookeeper to extract cluster
information like who is a the leader for a shard in a solr collection. To
create a CloudSolrClient all you specify is the zookeepers and which
collection you want to work with. Behind the scenes solrj will load balance
and send the request to the right "shard" in the cluster. The
CloudSolrClient is better if you have a cluster of multiple solr nodes
across multiple machines.
While in LBHttpSolrClient, load balancing is done using a simple
round-robin on the list of servers.
Hope this helps.
