-----------------------------------
Can not reproduce it anymore, can you try it again?
> Dataset in spark 2.0.0-SNAPSHOT missing columns
> -----------------------------------------------
>
> Key: SPARK-13326
> URL: https://issues.apache.org/jira/browse/SPARK-13326
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.0.0
> Reporter: koert kuipers
> Priority: Minor
>
> i noticed some things stopped working on datasets in spark 2.0.0-SNAPSHOT,
> and with a confusing error message (cannot resolved some column with input
> columns []).
> for example in 1.6.0-SNAPSHOT:
> {noformat}
> scala> val ds = sc.parallelize(1 to 10).toDS
> ds: org.apache.spark.sql.Dataset[Int] = [value: int]
> scala> ds.map(x => Option(x))
> res0: org.apache.spark.sql.Dataset[Option[Int]] = [value: int]
> {noformat}
> and same commands in 2.0.0-SNAPSHOT:
> {noformat}
> scala> val ds = sc.parallelize(1 to 10).toDS
> ds: org.apache.spark.sql.Dataset[Int] = [value: int]
> scala> ds.map(x => Option(x))
> org.apache.spark.sql.AnalysisException: cannot resolve 'value' given input
> columns: [];
