Review comment:
This issue happens when you have table properties say SORT_COLUMNS = "a,b"
Then the column name changed from a to a1, then it was changing SORT_COLUMNS = "a1" instead of SORT_COLUMNS = "a1,b". So, your current testcase cannot reproduce issue. so, add the testcase that gives issue without the change by keeping some table properties.
