[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).
