rdhabalia opened a new pull request #3919: [pulsar-broker] zk-isolation placement policy should be able to identify overlapped bookies
URL: https://github.com/apache/pulsar/pull/3919
 
 
   ### Motivation
   Right now, bookie-isolation-placement policy is not able to identify overlapped bookies which exist into given isolated group and in existing default group. Because of that user always has to update other default-groups when user creates new isolation group.
   eg:
   there could be a default-group present with rack-aware bookie info and this group contains all available bookies. However, if user wants to create isolated group with few bookies present into default-group then first user has to remove bookies from default-group and then have to create new isolated group else default-group bookies will be excluded.
   
   ### Modification
   
   To fix this issue, Placement-policy should be able to identify overlapped bookies from default-group and isolated-group and then remove those overlapped bookies from the excluded bookie list so, bk-client can select overlapped bookies from isolated group.
