             Summary: Raft term of a replica is set equals to leader even it failed to receive update on recovering
                 Key: SOLR-12433
                 URL: https://issues.apache.org/jira/browse/SOLR-12433

          Issue Type: Improvement

         Environment: When digging into RestartWhileUpdatingTest failure, I see that term of replicas is kinda mess up.

By design, the {{core_node24_recovering}} and {{core_node24}} should be always equals to each other. The reason here is {{ZkShardTerms.ensureTermsIsHigher}} also increase the {{core_node24_recovering}} is a higher number. This will lead to a case when a replica finished recovering but it won't be able to become active.
