Description

We're able to create new server via auto-scaling for our solr cluster 7.4 version. But the newly created server is not adding in our solr cluster automatically. Is there any settings or configurations we need to add in order to add the replica automatically in cluster for any collections.

commands used:

curl "http://localhost:8983/solr/admin/collections?action=CREATE&name=my_collection_3&numShards=1&replicationFactor=3&autoAddReplicas=true"

Currently 3 nodes are in our cluster and i'm trying to add 4th nod but its not getting added in solr 7.4 version. The same scenario is working fine in solr 7.5 version.

scaling policy used:

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"
}
]
}
}'

Note the same policy(2,3) not working in 7.4

if any new sever added into that cluster the data(collection) must be added as a replica in that cluster.[AddReplica Automatically added in version 7.5]

Kindly help me to resolve this case.

I need a exact trigger which will perform a AutoAddReplica Action
