Subject [jira] [Commented] (SPARK-10312) Enhance SerDe to handle atomic vector

Shivaram Venkataraman commented on SPARK-10312:
-----------------------------------------------

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.

> 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?
