             Summary: Consitence problem when in-sync replicas are DOWN
                 Key: SOLR-12011
                 URL: https://issues.apache.org/jira/browse/SOLR-12011
             Project: Solr
          Issue Type: Improvement
      Security Level: Public (Default Security Level. Issues are Public)
            Reporter: Cao Manh Dat
            Assignee: Cao Manh Dat


Currently, we will meet consistency problem when in-sync replicas are DOWN. For example:
1. A collection with 1 shard with 1 leader and 2 replicas
2. Nodes contain 2 replicas go down
3. The leader receives an update A, success
4. The node contains the leader goes down
5. 2 replicas come back
6. One of them become leader --> But they shouldn't become leader since they missed the update A
