Sean Owen commented on SPARK-13084:
-----------------------------------
Serialversionuid is generally a bad idea. It opens up a worse problem: you
claim compatibility when something isn't because you forget to update the
field. I don't think it's expected that a serialized RDD is compatible across
any different versions. I would be against this in general
> Utilize @SerialVersionUID to avoid local class incompatibility

> Adding @SerialVersionUID would overcome local class incompatibility across
> minor releases.
