-------------------------------------------
Summary: Creating a collection with implicit router adds shard
ranges to each shard
Key: SOLR-5296
URL: https://issues.apache.org/jira/browse/SOLR-5296
Project: Solr
Issue Type: Bug
Components: SolrCloud
Affects Versions: 4.5
Reporter: Shalin Shekhar Mangar
Assignee: Shalin Shekhar Mangar
Fix For: 5.0, 4.6
Creating a collection with implicit router adds shard ranges to each shard.
Using the Example A from SolrCloud wiki:
bq.
http://localhost:8983/solr/admin/collections?action=CREATE&name=myimplicitcollection3&numShards=2&maxShardsPerNode=5&router.name=implicit&shards=s1,s2&replicationFactor=2
The following clusterstate is created:
{quote}
"myimplicitcollection3":{
"shards":{
"s1":{
"range":"80000000-ffffffff",
"state":"active",
"replicas":{
"core_node1":{
"state":"active",
"base_url":"http://192.168.1.5:8983/solr";,
"core":"myimplicitcollection3_s1_replica2",
"node_name":"192.168.1.5:8983_solr"},
"core_node3":{
"state":"active",
"base_url":"http://192.168.1.5:7574/solr";,
"core":"myimplicitcollection3_s1_replica1",
"node_name":"192.168.1.5:7574_solr",
"leader":"true"}}},
"s2":{
"range":"0-7fffffff",
"state":"active",
"replicas":{
"core_node2":{
"state":"active",
"base_url":"http://192.168.1.5:8983/solr";,
"core":"myimplicitcollection3_s2_replica2",
"node_name":"192.168.1.5:8983_solr"},
"core_node4":{
"state":"active",
"base_url":"http://192.168.1.5:7574/solr";,
"core":"myimplicitcollection3_s2_replica1",
"node_name":"192.168.1.5:7574_solr",
"leader":"true"}}}},
"maxShardsPerNode":"5",
"router":{"name":"implicit"},
"replicationFactor":"2"}
{quote}
Collections with implicit router should not have shard ranges at all. Note that
the createshard API does the right thing.
