Description:
There seems to be a regression between 1.6.0 and 1.6.1 (snapshot build). By
default a scala {{Seq\[Double\]}} is mapped by Spark as an ArrayType with
nullable element
{noformat}
|-- valuations: array (nullable = true)
||-- element: double (containsNull = true)
{noformat}
This could be read back to as a Dataset in Spark 1.6.0
{code}
val df = sqlContext.table("valuations").as[Valuation]
{code}
But with Spark 1.6.1 the same fails with
{code}
val df = sqlContext.table("valuations").as[Valuation]
org.apache.spark.sql.AnalysisException: cannot resolve 'cast(valuations as
array)' due to data type mismatch: cannot cast
ArrayType(DoubleType,true) to ArrayType(DoubleType,false);
{code}
Here's the classes I am using
{code}
case class Valuation(tradeId : String,
counterparty: String,
nettingAgreement: String,
wrongWay: Boolean,
valuations : Seq[Double], /* one per scenario */
timeInterval: Int,
jobId: String) /* used for hdfs partitioning */
val vals : Seq[Valuation] = Seq()
val valsDF = sqlContext.sparkContext.parallelize(vals).toDF
valsDF.write.partitionBy("jobId").mode(SaveMode.Overwrite).saveAsTable("valuations")
{code}
even the following gives the same result
{code}
val valsDF = vals.toDS.toDF
{code}
was:

Target Version/s: 1.6.1
Priority: Blocker (was: Major)
I'm temporarily marking this as a 1.6.1 blocker so that we make sure to
investigate and triage before cutting an RC. /cc [~marmbrus]
