> ----------------------------------------------------------
>
> Key: SPARK-8903
> URL: https://issues.apache.org/jira/browse/SPARK-8903
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.4.1
> Reporter: Josh Rosen
> Assignee: Josh Rosen
> Priority: Blocker
>
> The backport of SPARK-8803 to branch-1.4 contains an error:
> It calls
> {code}
> countsRow.setString(0, cleanElement(col1Item.toString))
> {code}
> instead of
> {code}
> countsRow.setString(0, cleanElement(col1Item))
> {code}
> which leads to a NullPointerException when col1Item == null.
