> Key: SPARK-7178
> URL: https://issues.apache.org/jira/browse/SPARK-7178
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 1.3.1
> Reporter: Chris Fregly
> Labels: dataframe
>
> AND and OR are not straightforward when using the new DataFrame API.
> the current convention - accepted by Pandas users - is to use the bitwise &
> and | instead of AND and OR. when using these, however, you need to wrap
> each expression in parenthesis to prevent the bitwise operator from
> dominating.
