[GitHub] [druid] didip opened a new issue #11639: When Druid deletes a record in Zookeeper, it should make sure that the record is actually deleted.

didip opened a new issue #11639:
URL: https://github.com/apache/druid/issues/11639


   ### Affected Version
   
   0.21.1
   
   ### Description
   
   We have this problem that we internally called "ghost IPs" where records of IP addresses exist in Zookeeper but don't exist in reality. This issue manifests itself in many subtle breaking behaviors:
   
   1. Middle Managers slowly losing capacity.
   2. Entire query serving feature breaks because historical nodes book keeping became incorrect.
