Apache Spark reassigned SPARK-6999:
-----------------------------------
Assignee: (was: Apache Spark)
> infinite recursion with createDataFrame(JavaRDD[Row], java.util.List[String])
> -----------------------------------------------------------------------------
>
> Key: SPARK-6999
> URL: https://issues.apache.org/jira/browse/SPARK-6999
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.3.0
> Reporter: Justin Uang
> Priority: Blocker
>
> It looks like
> {code}
> def createDataFrame(rowRDD: JavaRDD[Row], columns: java.util.List[String]):
> DataFrame = {
> createDataFrame(rowRDD.rdd, columns.toSeq)
> }
> {code}
> is in fact an infinite recursion because it calls itself. Scala implicit
> conversions convert the arguments back into a JavaRDD and a java.util.List.
> {code}
