             Summary: API to flag a solr node NOT READY for requests
                 Key: SOLR-16722
                 URL: https://issues.apache.org/jira/browse/SOLR-16722
             Project: Solr
          Issue Type: New Feature
      Security Level: Public (Default Security Level. Issues are Public)
            Reporter: Jan Høydahl


Spinoff from solr operator PR [https://github.com/apache/solr-operator/issues/529]

When solr-operator performs a rolling restart or rolling upgrade, it will stop one node at a time, but SolrJ (both external and internal) will continue sending traffic to the node until requests start failing, since at the time SolrJ picks up the "live_nodes" change, it is too late.

While the operator PR mentioned above will prevent external requests through the k8s service to the draining node, it will not prevent internal traffic.

This issue thus aims to introduce some API or mechanism to flag a Solr node as NOT READY for traffic.
