             Summary: 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:

> a <- as.Date(c("2016-11-11", "NA"))
> b <- as.data.frame(a)
> c <- createDataFrame(b)
> dim(c)
