-----------------------------------------------
SInce the SerDe is an internal API I think its fine to not support some of the
use cases. We can close this issue as `Will not fix` if you think thats ok.
> Enhance SerDe to handle atomic vector
> -------------------------------------
>
> Key: SPARK-10312
> URL: https://issues.apache.org/jira/browse/SPARK-10312
> Project: Spark
> Issue Type: Improvement
> Components: SparkR
> Affects Versions: 1.4.1
> Reporter: Sun Rui
>
> Currently, writeObject() does not handle atomic vector well. For an atomic
> vector, it treats it like a scalar object. For example, if you pass c(1:10)
> into writeObject, it will write a single integer as 1. You have to explicitly
> cast an atomic vector, for example, as.list(1:10), to a list, if you want to
> write the whole vector.
> Could we enhance the SerDe that when the object is an atomic vector whose
> length >1, convert it to a list and then write?
