>             Project: Spark
>          Issue Type: Improvement
>          Components: SQL
>    Affects Versions: 2.0.0

> This was found in https://github.com/apache/spark/pull/12494.
> Currently, most of options in data sources throws {{NullPointerException}} when given value is {{null}}.
> For example, the codes below:
> {code}
> sqlContext.read
>       .format("csv")
>       .option("compression", null)
> {code}
> throws an exception below:
> {code}
> java.lang.NullPointerException was thrown.
> java.lang.NullPointerException
>     at org.apache.spark.sql.execution.datasources.csv.CSVOptions.getChar(CSVOptions.scala:32)
>     at org.apache.spark.sql.execution.datasources.csv.CSVOptions.<init>(CSVOptions.scala:68)
>     at org.apache.spark.sql.execution.datasources.csv.DefaultSource.prepareWrite(DefaultSource.scala:86)
> ...
> {code}
> while some of options such as {{nullValue}} in CSV data source accepts {{null}} .
> So, the options throwing {{NullPointerException}} when it sets to {{null}} might have to be handled separately for each data source.
