Tejas Patil updated SPARK-12926:
--------------------------------
Description:
Users unknowingly try to set core Spark configs in sqlContext but later realise
that it didn't work.
scala> sqlContext.sql("SET spark.shuffle.memoryFraction=0.4")
res3: org.apache.spark.sql.DataFrame = [key: string, value: string]
scala> sc.getConf.get("spark.shuffle.memoryFraction")
java.util.NoSuchElementException: spark.shuffle.memoryFraction
at org.apache.spark.SparkConf$$anonfun$get$1.apply(SparkConf.scala:193)
at org.apache.spark.SparkConf$$anonfun$get$1.apply(SparkConf.scala:193)
at scala.Option.getOrElse(Option.scala:120)
at org.apache.spark.SparkConf.get(SparkConf.scala:193)
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 :
