Description
ArrayType, MapType and StructureType
We can infer the correct schema for them, but the serialization can not handle them well.
From Davies in https://sparkr.atlassian.net/browse/SPARKR-230
ArrayType could be c("ab", "ba"), we will serialize it as character. We does not support deserialize env in R (serialize Map[] in Scala). So all the three do not work.
