Apache Spark reassigned SPARK-21092:
------------------------------------
Assignee: Reynold Xin (was: Apache Spark)
> Wire SQLConf in logical plan and expressions
> --------------------------------------------
>
> Key: SPARK-21092
> URL: https://issues.apache.org/jira/browse/SPARK-21092
> Project: Spark
> Issue Type: New Feature
> Components: SQL
> Affects Versions: 2.2.0
> Reporter: Reynold Xin
> Assignee: Reynold Xin
>
> It is really painful to not have configs in logical plan and expressions. We
> had to add all sorts of hacks (e.g. pass SQLConf explicitly in functions).
> This ticket exposes SQLConf in logical plan, using a thread local variable
> and a getter closure that's set once there is an active SparkSession.
