[jira] [Created] (HBASE-11945) Client writes may be reordered under contention

Todd Lipcon created HBASE-11945:
-----------------------------------

             Summary: Client writes may be reordered under contention
                 Key: HBASE-11945
                 URL: https://issues.apache.org/jira/browse/HBASE-11945
             Project: HBase
          Issue Type: Bug
          Components: regionserver
    Affects Versions: 0.98.6
            Reporter: Todd Lipcon


I haven't seen this bug in practice, but I was thinking about this a bit and think there may be a correctness issue with the way that we handle client batches which contain multiple operations which touch the same row. The client expects that these operations will be performed in the same order they were submitted, but under contention I believe they can get arbitrarily reordered, leading to incorrect results.
