> SparkR serialize "NA" throws exception

> Key: SPARK-18011
> URL: https://issues.apache.org/jira/browse/SPARK-18011
> Project: Spark
> Issue Type: Bug
> Components: SparkR
> Reporter: Miao Wang

> For some versions of R, if Date has "NA" field, backend will throw negative
> index exception.
> To reproduce the problem:
> {code}
> > a <- as.Date(c("2016-11-11", "NA"))
> > b <- as.data.frame(a)
> > c <- createDataFrame(b)
> > dim(c)
