             Summary: Sub shard leader should not accept any updates from parent after it goes active
                 Key: SOLR-4795
                 URL: https://issues.apache.org/jira/browse/SOLR-4795
             Project: Solr
          Issue Type: Bug
          Components: SolrCloud
    Affects Versions: 4.3
            Reporter: Shalin Shekhar Mangar
            Assignee: Shalin Shekhar Mangar
            Priority: Minor
             Fix For: 4.4


The sub shard leaders accept any update from a parent as long as their range is a subset of parent's range. A sub shard can continue to accept updates from parent even after it has gone active which can lead to inconsistencies. This affects partial updates (think counters) the most but can also lead to out-of-order updates to the same document.
