Yan Facai (颜发才) commented on SPARK-20787:
-----------------------------------------
It seems that the exception is raised when serialization. Microsecond is used
as internal representation of Timestamp in pyspark.
As scala works well, hence there must be something wrong in python code.
<code>
scala> val df = Seq("05/26/1800 01:01:01").toDF("dt")
scala> val ts = unix_timestamp($"dt","MM/dd/yyyy HH:mm:ss").cast("timestamp")
scala> df.withColumn("ts", ts).show(false)
+-------------------+---------------------+
|dt |ts |
+-------------------+---------------------+
|05/26/1800 01:01:01|1800-05-26 01:01:01.0|
+-------------------+---------------------+
