[GitHub] spark issue #21911: [SPARK-24940][SQL] Coalesce Hint for SQL Queries

Github user gatorsmile commented on the issue:

    @jzhuge I knew all the DBMS have the hints. Do you know whether any system has a hint like `Coalesce`? Could you check the systems that have sophisticated hints like Oracle and DB2?
