Ashutosh Chauhan commented on HIVE-9412:
----------------------------------------
These clauses have a bit tricky semantics. For new tests in golden file, Navis
can you also verify resultset for these queries on postgres, so that we have a
confidence that result set for these test queries is correct.
> Window clause ROW BETWEEN for PRECEDING does not work

> Key: HIVE-9412
> URL: https://issues.apache.org/jira/browse/HIVE-9412
> Project: Hive
> Issue Type: Bug
> Components: Parser
> Affects Versions: 0.14.0, 0.13.1
> Environment: CDH 5.3 or HDP 2.2
> Reporter: Will Du

>
> 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)
