Subject Re: Failed to 'collect_set' with dataset in spark 1.6
Date Mon, 01 Feb 2016 17:41:51 GMT
Running your sample in spark-shell built in master branch, I got:

scala> val dataset = sc.parallelize(Seq(RecordExample(1, "apple"),
RecordExample(2, "orange"))).toDS()
org.apache.spark.sql.AnalysisException: Unable to generate an encoder for
inner class `RecordExample` without access to the scope that this class was
defined in. Try moving this class out of its parent class.;
