Description

These components are,

• Available on every node
• deployed at the CoreContainer level
• Available only at V2 endpoint /api/node/ext/<plugin-name> (v2 style)
• Should implement the SolrRequestHandler interface

The configuration is persisted in clusterprops.json

curl -X POST -H 'Content-type:application/json' --data-binary '{
  "add-requesthandler": {
      "name": "foo", 
      "class" : "fully.qualified.ClassName"
    
  }
}' http://localhost:8983/api/cluster

delete it using

curl -X POST -H 'Content-type:application/json' --data-binary '{
  "delete-requesthandler": "foo"
}' http://localhost:8983/api/cluster
