------------------------------------
[~zsxwing] I may be confused then. Which issue I am hitting if not this one?
[ERROR] [05/08/2017 13:25:27.735] [Sake-akka.actor.default-dispatcher-3]
[akka.actor.ActorSystemImpl(Sake)] Error during processing of request:
'spark.sql.execution.id is already set'. Completing with 500 Internal Server
Error response. To change default exception handling behavior, provide a custom
ExceptionHandler.

> Key: SPARK-13747
> URL: https://issues.apache.org/jira/browse/SPARK-13747
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.0.0, 2.0.1
> Reporter: Shixiong Zhu
> Assignee: Shixiong Zhu
>
> Run the following codes may fail
> {code}
> (1 to 100).par.foreach { _ =>
> println(sc.parallelize(1 to 5).map { i => (i, i) }.toDF("a", "b").count())
> }

> at org.apache.spark.sql.DataFrame.collect(DataFrame.scala:1385)
> {code}
> This is because SparkContext.runJob can be suspended when using a
> ForkJoinPool (e.g.,scala.concurrent.ExecutionContext.Implicits.global) as it
> calls Await.ready (introduced by https://github.com/apache/spark/pull/9264).
> So when SparkContext.runJob is suspended, ForkJoinPool will run another task
> in the same thread, however, the local properties has been polluted.
