-------------------------------
Assignee: Bogdan Raducanu
Target Version/s: 2.2.0
Priority: Blocker (was: Major)
> extend hint syntax to support any expression, not just identifiers or strings
> -----------------------------------------------------------------------------
>
> Key: SPARK-20854
> URL: https://issues.apache.org/jira/browse/SPARK-20854
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.2.0
> Reporter: Bogdan Raducanu
> Assignee: Bogdan Raducanu
> Priority: Blocker
>
> Currently the SQL hint syntax supports as parameters only identifiers while
> the Dataset hint syntax supports only strings.
> They should support any expression as parameters, for example numbers. This
> is useful for implementing other hints in the future.
> Examples:
> {code}
> df.hint("hint1", Seq(1, 2, 3))
> df.hint("hint2", "A", 10000)
> sql("select /*+ hint1((1,2,3)) */")
> sql("select /*+ hint2('A', 10000) */")
> {code}
