Hi, I have created 8 shards on a collection named as ***wikingram**. Now at that time, I were not created any replica. Now, I want to add a replica on each shard. How can I do? I created this - ** sudo curl http://localhost:8983/solr/admin/collections?action=ADDREPLICA&collection=wikingram&shard=shard1&node=localhost:8983_solr** but it is not working.
It throws errror - <response> <lst name="responseHeader"> <int name="status">400</int> <int name="QTime">86</int> </lst> <str name="Operation ADDREPLICA caused exception:">org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Could not find collection : null</str> <lst name="exception"> <str name="msg">Could not find collection : null</str> <int name="rspCode">400</int> </lst> <lst name="error"> <str name="msg">Could not find collection : null</str> <int name="code">400</int> </lst> </response> Any help on this?
