Summary: Further changes to avoid PRS entry writes from overseer
Key: SOLR-16478
URL: https://issues.apache.org/jira/browse/SOLR-16478
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Components: SolrCloud
Affects Versions: 9.1
Reporter: Patson Luk
For further improvements based on
https://issues.apache.org/jira/browse/SOLR-16414, there are places that we
should remove PRS entry operations from overseer:
1. In `ZkController#unregister`, the PRS hosting node should remove the PRS
entries from ZK, as overseer no longer does so as in the change of
https://github.com/apache/solr/pull/1019/files#diff-b08497f972c47127009b59dc49de322698312c08ee53684d6e916db256db16a2L149
2. We should as well remove the PRS entries ops from Overseer in
`SliceMutator#addReplica`
