----------------------------------
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.
