     new 3959c31  [HOTFIX] Fix CarbonHive CI Failures
3959c31 is described below

commit 3959c319ff447c63c09d72eff29a3823aef234c4
Author: haomarch <marchpure@126.com>
AuthorDate: Wed Mar 11 17:34:02 2020 +0800

    [HOTFIX] Fix CarbonHive CI Failures
    
    Why is this PR needed?
    1. In some cases, the carbonhive ci failes because of the permission issue.
    2. The csv filepath in the TestCase is wrong.
    3. The complex type parsing has bugs.
    4. When rowcount of resultset is zero, no error is throwed.
    
    What changes were proposed in this PR?
    1. Give 777 permission to carbonhive warehouse dirs.
    2. Repair the csv filepath and complex typeparsing.
    3. Verify the rowcount of resultset
    
    Does this PR introduce any user interface change?
    No
    
    Is any new testcase added?
    No
    
    This closes #3665
