> When window clause with ROWS is used between two proper PRECEDING boundaries, Hive reports
syntax errors as following examples.
> --For example 1
> SELECT name, dept_num, salary,
> MAX(salary) OVER (PARTITION BY dept_num ORDER BY 
> name ROWS BETWEEN 2 PRECEDING AND 1 PRECEDING) win4_alter
> FROM employee_contract;
> Error: Error while compiling statement: FAILED: SemanticException Failed to breakup Windowing
invocations into Groups. At least 1 group must only depend on input columns. Also check for
circular dependencies.
> Underlying error: Window range invalid, start boundary is greater than end boundary:
window(start=range(2 PRECEDING), end=range(1 PRECEDING)) (state=42000,code=40000)
> --For example 2
> SELECT name, dept_num, salary,
> MAX(salary) OVER (PARTITION BY dept_num ORDER BY 
> name ROWS BETWEEN UNBOUNDED PRECEDING AND 1 PRECEDING) win1
> FROM employee_contract;
> Error: Error while compiling statement: FAILED: SemanticException End of a WindowFrame
cannot be UNBOUNDED PRECEDING (state=42000,code=40000)
