             Summary: add retry strategy in cache sync 
                 Key: KYLIN-2858
                 URL: https://issues.apache.org/jira/browse/KYLIN-2858
             Project: Kylin
          Issue Type: Improvement
          Components: Metadata
    Affects Versions: v2.1.0, v2.0.0
            Reporter: chaoli
            Assignee: chaoli


since there may be an situation that when sync request call a node that is down 
temporary and is restarting, sync cache may fail. So I add a retry strategy to 
avoid that situation
