Hi, We have 5 shards with replication factor 2 (total 10 jvm instances). Our shards are named (shardid) shard1,shard2,shard3,shar4 and shar5 and collection name is collection1. When we execute this command:
curl --proxy '' "http://$HOST_NAME:8983/solr/admin/collections?action=SPLITSHARD&collection=collection1&shard=shard1"; We get this error: <lst name="failure"> <str>org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException:Error CREATEing SolrCore 'collection1_shard1_0_replica1': Core with same data dir 'collection1' already exists.</str> <str>org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException:Error CREATEing SolrCore 'collection1_shard1_1_replica1': Core with same data dir 'collection1' already exists.</str> <str>org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException:core not found:collection1_shard1_0_replica1</str> <str>org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException:core not found:collection1_shard1_1_replica1</str> <str>org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException:Server at http://$HOST:8983/solr returned non ok status:500, message:Server Error</str> <str>org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException:Server at http://$HOST:8983/solr returned non ok status:500, message:Server Error</str> <str>org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException:Server at http://$HOST:8983/solr returned non ok status:500, message:Server Error</str> <str>org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException:Error CREATEing SolrCore 'collection1_shard1_1_replica2': Unable to create core: collection1_shard1_1_replica2</str> <str>org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException:Error CREATEing SolrCore 'collection1_shard1_0_replica2': Core with same data dir 'collection1' already exists.</str> <str>org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException:core not found:collection1_shard1_0_replica1</str> <str>org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException:core not found:collection1_shard1_1_replica1</str> </lst> </response> Does the collection name has to be different than existing collection? If yes, why is that? We're not creating a new collection. We just want to split existing shard. Thanks much!
