Apache Spark reassigned SPARK-40797:
------------------------------------
Assignee: Apache Spark
> Force grouped import onto single line with Scalafmt
> ---------------------------------------------------
>
> Key: SPARK-40797
> URL: https://issues.apache.org/jira/browse/SPARK-40797
> Project: Spark
> Issue Type: Improvement
> Components: Build
> Affects Versions: 3.4.0
> Reporter: Martin Grund
> Assignee: Apache Spark
> Priority: Major
>
> When using the scalafmt.conf file as provided by the project repository to
> organize and optimize imports there is a case in which un-desired behavior
> appears.
> If the import group does not fit on a single line, Scalafmt will by default
> try to bin-pack and then break out over mulitple lines.
> For example:
> import org.apache.spark.sql.catalyst.analysis.\{UnresolvedAlias,
> UnresolvedAttribute, UnresolvedFunction, UnresolvedRelation,
> UnresolvedStar}{{{}{}}}will become
> import org.apache.spark.sql.catalyst.analysis.\{
> UnresolvedAlias,
> UnresolvedAttributed,
> ...
> }{{{}{}}}In previous code reviews this has been marked as departing from the
> consistency of the Spark code base even when using the provided scalafmt.conf.
>
> Scalafmt allows to configure this by setting an option
>
> {code:java}
> importSelectors = "singleLine"{code}
