Description

Custom components to be loaded at a CorContainer level

How to configure this?

curl -X POST -H 'Content-type:application/json' --data-binary '
{
  "add-runtimelib": {
      "name": "lib-name" ,
      "url" : "http://host:port/url/of/jar",
      "sha512":"<the-sha512>"
  }
}' http://localhost:8983/api/cluster

How to update your jars?

curl -X POST -H 'Content-type:application/json' --data-binary '
{
  "update-runtimelib": {
      "name": "lib-name" ,
      "url" : "http://host:port/url/of/jar",
      "sha512":"<the-new-sha512>"
  }
}' http://localhost:8983/api/cluster

This only loads the components used in CoreContainer and it does not need to restart the Solr node

The configuration lives in the file /clusterprops.json in ZK.
