             Summary: Occasional failure to query the real-time model, reporting NPE
                 Key: KYLIN-5319
                 URL: https://issues.apache.org/jira/browse/KYLIN-5319
             Project: Kylin

          Components: Query Engine
            Reporter: Jiale He
             Fix For: 5.0-alpha


这个问题是因为
Segment Merge 完毕后，元数据更新结束的节点大量并发查询，
FilePruner中DataFlow变量的Segment元数据懒加载导致的。
因为懒加载导致dataflow中元数据不一致。
