[jira] [Created] (KYLIN-5460) When resource group is turned on, using EnhancedUnitOfWork to write metadata might fail

Ruixuan Zhang created KYLIN-5460:
------------------------------------

             Summary: When resource group is turned on, using EnhancedUnitOfWork to write metadata might fail
                 Key: KYLIN-5460
                 URL: https://issues.apache.org/jira/browse/KYLIN-5460
             Project: Kylin
          Issue Type: Improvement
          Components: Metadata
    Affects Versions: 5.0-alpha
            Reporter: Ruixuan Zhang
            Assignee: Ruixuan Zhang
             Fix For: 5.0-alpha


When resource group is turned on, using EnhancedUnitOfWork to write metadata will check if current owner has the write permission, that is, if the node is in the build resource group. The new feature of providing more flexible runtime join will force KYLIN to go into maintenance mode when using script to update and write metadata, this will have mocked node IP:0000 occupy the epoch and since the mocked node is not in the build resource group, which causes write failure.
