Hi Ravi, I just tried it out and here's my understanding:
1. Starting Solr with -c starts Solr in cloud mode. This is used to start Solr with an embedded zookeeper. 2. Starting Solr with -z starts Solr in cloud mode, with the zk connection string you specify. You don't need to explicitly specify -c in this case. The help text there needs a bit of fixing though * -z <zkHost> ZooKeeper connection string; only used when running in SolrCloud mode using -c* * To launch an embedded ZooKeeper instance, don't pass this parameter.* *"only used when running in SolrCloud mode using -c" *needs to be rephrased or removed. Can you create a JIRA for the same?
