This is the correct way to do it.The timestamp that you mentioned was not
correct:

scala> val ts1 = from_unixtime($"ts"/1000, "yyyy-MM-dd")
ts1: org.apache.spark.sql.Column = fromunixtime((ts / 1000),yyyy-MM-dd)

scala> val finaldf = df.withColumn("ts1",ts1)
finaldf: org.apache.spark.sql.DataFrame = [client_id: string, ts: string,
ts1: string]

scala> finaldf.show
+--------------------+-------------+----------+
|           client_id|           ts|       ts1|
+--------------------+-------------+----------+
|cd646551-fceb-416...|1477989416803|2016-11-01|
|3bc61951-0f49-43b...|1477983725292|2016-11-01|
|688acc61-753f-4a3...|1479899459947|2016-11-23|
|5ff1eb6c-14ec-471...|1479901374026|2016-11-23|
+--------------------+-------------+----------+
