[SPARK-10684] [SQL] StructType.interpretedOrdering need not to be serialized
Kryo fails with buffer overflow even with max value (2G).
{noformat}
org.apache.spark.SparkException: Kryo serialization failed: Buffer
overflow. Available: 0, required: 1
Serialization trace:
containsChild (org.apache.spark.sql.catalyst.expressions.BoundReference)
child (org.apache.spark.sql.catalyst.expressions.SortOrder)
array (scala.collection.mutable.ArraySeq)
ordering (org.apache.spark.sql.catalyst.expressions.InterpretedOrdering)
interpretedOrdering (org.apache.spark.sql.types.StructType)
schema (org.apache.spark.sql.catalyst.expressions.GenericRowWithSchema). To
avoid this, increase spark.kryoserializer.buffer.max value.
