             Summary: Updating the model metadata when getting the model list 
with high concurrency may cause the model metadata cache to be abnormal and the 
model status to become broken
                 Key: KYLIN-5845
                 URL: https://issues.apache.org/jira/browse/KYLIN-5845
             Project: Kylin
          Issue Type: Bug
          Components: Metadata
    Affects Versions: 5.0-beta
            Reporter: Zhimin Wu
            Assignee: Zhimin Wu
             Fix For: 5.0.0


Fix the issue caused by concurrent initialization by checking if the model has 
already been initialized. If so, skip the initialization step. Otherwise, 
perform a copy operation first and then initialize the model to avoid 
concurrent initialization problems.
