The exception "No live SolrServers" is being thrown when trying to create a new
Collection ( code at end of this mail). On the CloudSolrServer request method,
we have this line
"ClientUtils.appendMap(coll, slices, clusterState.getSlices(coll));" where
"coll" is the new collection I am trying to create and hence
clusterState.getSlices(coll)); is returning null.
And then the loop of the slices which adds to the urlList never happens and
hence the LBHttpSolrServer created in the CloudSolrServer has a null url list
in the constructor.
This is giving the "No live SolrServers" exception.
What I am missing?
Instead of passing the CloudSolrServer to the create.process, if I pass the
LBHttpSolrServer (server.getLbServer()), the collection gets created but only
on one server.
My code to create a new Cloud Server and new Collection:-
String[] urls =
{"http://127.0.0.1:8983/solr/","http://127.0.0.1:8900/solr/","http://127.0.0.1:7500/solr/","http://127.0.0.1:7574/solr/"};
CloudSolrServer server = new CloudSolrServer("127.0.0.1:2181", new
LBHttpSolrServer(urls));
server.getLbServer().getHttpClient().getParams().setParameter(CoreConnectionPNames.CONNECTION_TIMEOUT,
5000);
server.getLbServer().getHttpClient().getParams().setParameter(CoreConnectionPNames.SO_TIMEOUT,
20000);
server.setDefaultCollection(collectionName);
server.connect();
CoreAdminRequest.Create create = new CoreAdminRequest.Create();
create.setCoreName("myColl");
create.setCollection("myColl");
create.setInstanceDir("defaultDir");
create.setDataDir("myCollData");
create.setNumShards(2);
create.process(server); //Exception No live SolrServers is thrown here
Thanks
Jay

Tried Wireshark yet to see what host/port it is trying to connect and why it
fails? It is a complex tool, but well worth learning.
