Question

我们能够通过自动扩展为solr集群7.4版本创建新服务器。但是新创建的服务器不会自动添加到我们的solr集群中。是否需要添加任何设置或配置，以便为任何集合将副本自动添加到群集中。

使用的

命令：卷曲“ http://localhost:8983/solr/admin/collections?action=CREATE&name=my_collection_3&numShards=1&replicationFactor=3&autoAddReplicas=true”

当前在我们的集群中有3个节点，我正在尝试添加第4个nod，但是在solr 7.4版本中没有添加。相同的方案在solr 7.5版本中工作正常。

使用的扩展策略：

1)
curl http://localhost:8983/solr/admin/autoscaling -H 'Content-type:application/json' -d '{
 "set-cluster-policy" : [{
  "replica" : "1",
  "shard" : "#EACH",
  "node" : "#ANY",
 }]
}'

2)###Node Added Trigger
curl http://localhost:8983/solr/admin/autoscaling -H 'Content-type:application/json' -d '{
 "set-trigger": {
  "name" : "node_added_trigger",
  "event" : "nodeAdded",
  "waitFor" : "5s",
  "preferredOperation": "ADDREPLICA",
  "enabled" : true,
  "actions" : [
   {
    "name" : "compute_plan",
    "class": "solr.ComputePlanAction"
   },
   {
    "name" : "execute_plan",
    "class": "solr.ExecutePlanAction"
   }
  ]
 }
}'

3)###Node Lost Trigger
curl http://localhost:8983/solr/admin/autoscaling -H 'Content-type:application/json' -d '{
 "set-trigger": {
  "name" : "node_lost_trigger",
  "event" : "nodeLost",
  "waitFor" : "5s",
  "preferredOperation": "DELETENODE",
  "enabled" : true,
  "actions" : [
   {
    "name" : "compute_plan",
    "class": "solr.ComputePlanAction"
   },
   {
    "name" : "execute_plan",
    "class": "solr.ExecutePlanAction"
   }
  ]
 }
}'

请注意，相同的策略（2,3）在7.4中不起作用

如果在该集群中添加了任何新服务器，则必须将数据（集合）作为副本添加到该集群中。[AddReplica在7.5版中自动添加]
