> Let’s have following json
> {code}
> val rdd = sc.parallelize("""{"ts":1452386229}""" :: Nil)
> {code}
> Spark sql casts int to timestamp treating int value as a number of seconds.
> https://issues.apache.org/jira/browse/SPARK-11724
> {code}
> scala> sqlContext.read.json(rdd).select($"ts".cast(TimestampType)).show
> +--------------------+
> |                  ts|
> +--------------------+

> +--------------------+
> {code}
> However parsing json with schema gives different result
> {code}
> scala> val schema = (new StructType).add("ts", TimestampType)
> schema: org.apache.spark.sql.types.StructType = StructType(StructField(ts,TimestampType,true))
> scala> sqlContext.read.schema(schema).json(rdd).show
> +--------------------+
> |                  ts|
> +--------------------+
