Josh Rosen resolved SPARK-6513.
-------------------------------
Resolution: Won't Fix
> Add zipWithUniqueId (and other RDD APIs) to RDDApi
> --------------------------------------------------
>
> Key: SPARK-6513
> URL: https://issues.apache.org/jira/browse/SPARK-6513
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 1.3.0
> Environment: Windows 7 64bit, Scala 2.11.6, JDK 1.7.0_21 (though I
> don't think it's relevant)
> Reporter: Eran Medan
> Priority: Minor
>
> It will be nice if we could treat a Dataframe just like an RDD (wherever it
> makes sense)
> *Worked in 1.2.1*
> {code}
> val sqlContext = new HiveContext(sc)
> import sqlContext._
> val jsonRDD = sqlContext.jsonFile(jsonFilePath)
> jsonRDD.registerTempTable("jsonTable")
> val jsonResult = sql(s"select * from jsonTable")
> val foo = jsonResult.zipWithUniqueId().map {
> case (Row(...), uniqueId) => // do something useful
> ...
> }
> foo.registerTempTable("...")
> {code}
> *Stopped working in 1.3.0*
> {code}
> jsonResult.zipWithUniqueId() //since RDDApi doesn't implement that method
> {code}
> **Not working workaround:**
> although this might give me an {{RDD\[Row\]}}:
> {code}
> jsonResult.rdd.zipWithUniqueId()
> {code}
> Now this won't work obviously since {{RDD\[Row\]}} does not have a
> {{registerTempTable}} method of course
> {code}
> foo.registerTempTable("...")
> {code}
> (see related SO question:
> http://stackoverflow.com/questions/29243186/is-this-a-regression-bug-in-spark-1-3)
> EDIT: changed from issue to enhancement request
