Hi I am installing SolrCloud with 3 External Zookeeper(localhost:2181,localhost:2182,localhost:2183) and 2 Tomcats(localhost:8181,localhost:8182) all available on a single Machine(Just for getting started). By Following these links
http://myjeeva.com/solrcloud-cluster-single-collection-deployment.html http://wiki.apache.org/solr/SolrCloudTomcat I have got the Solr UI on the machine pointing to http://localhost:8181/solr/#/~cloud In the Cloud Graph View it is coming with mycollection | |_ shard1 |_ shard2 But both the shards are empty and showing no cores or replica. Following http://myjeeva.com/solrcloud-cluster-single-collection-deployment.htmlblog, I have been successful till starting tomcat, since after the section "Creating Collection, Shard(s), Replica(s) in SolrCloud" I am facing the problem. Giving command to create replica for the shard using *curl 'http://localhost:8181/solr/admin/cores?action=CREATE&name=shard1-replica-2&collection=mycollection&shard=shard1 <http://localhost:8181/solr/admin/cores?action=CREATE&name=shard1-replica-2&collection=mycollection&shard=shard1>'* it is giving error <response> <lst name="responseHeader"><int name="status">400</int><int name="QTime">137</int></lst><lst name="error"><str name="msg"> *Error CREATEing SolrCore 'shard1-replica-2': 192.168.2.183:8182_solr_shard1-replica-2 is removed* </str><int name="code">400</int></lst> </response> Has anybody went through this issue? Regards
