             Summary: StructType.interpretedOrdering need not to be serialized
                 Key: SPARK-10684

    Affects Versions: 1.5.0
            Reporter: Navis
            Priority: Minor


Kryo fails with buffer overflow even with max value (2G).

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.
