> SQLContext to disallow users passing non-sql configs
> ----------------------------------------------------
>
> Key: SPARK-12926
> URL: https://issues.apache.org/jira/browse/SPARK-12926
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 1.6.0
> Reporter: Tejas Patil
> Priority: Trivial
>
> Users unknowingly try to set core Spark configs in sqlContext but later
> realise that it didn't work.
> {color:red}
> scala> sqlContext.sql("SET spark.shuffle.memoryFraction=0.4")
> res3: org.apache.spark.sql.DataFrame = [key: string, value: string]
> scala> sqlContext.getConf.get("spark.shuffle.memoryFraction")
> java.util.NoSuchElementException: spark.shuffle.memoryFraction

> We could do this:
> - for configs starting with "spark.", allow only if it starts with
> "spark.sql.". Otherwise disallow.
> - allow anything else.
> This will be a simple change in SqlConf :
