    [HOTFIX] Fix a random CI failure in HiveCarbonTest: 'metastore_db' already exists
    
    Why is this PR needed?
    HiveCarbonTest will fails randomly, the exception message is as below:
    Dictionary 'metastore_db' exists. However, it does not contain the expected 'service.properties' file.
    The root cause maybe there is stale metastore_db dictionary in the filesystem.
    
    What changes were proposed in this PR?
    Clean the metastore_db dictionary before testcase running.
    
    Does this PR introduce any user interface change?
    No
    
    Is any new testcase added?
    No
    
    This closes #4028
