----------------------------------

             Summary: KuduSession.flush can return null or presumably an empty 
list
                 Key: KUDU-1402
                 URL: https://issues.apache.org/jira/browse/KUDU-1402
             Project: Kudu
          Issue Type: Improvement
    Affects Versions: 0.7.0
            Reporter: Brock Noland
            Priority: Minor


I was surprised that {{KuduSession.flush}} can return null since it's returning 
a list. It'd be nicer to return an empty list instead of null.
