> Key: SPARK-24442
> URL: https://issues.apache.org/jira/browse/SPARK-24442
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.2.0, 2.3.0
> Reporter: Andrew K Long
> Priority: Minor
> Attachments: spark-adjustable-display-size.diff
>
> Original Estimate: 12h
> Remaining Estimate: 12h
>
> Currently the number of characters displayed when a user runs the .show() function on a data frame is hard coded. The current default is too small when used with wider console widths. This fix will add two parameters.
>
> parameter: "spark.show.default.number.of.rows" default: "20"
> parameter: "spark.show.default.truncate.characters.per.column" default: "20"
>
> This change will be backwords compatible and will not break any existing functionality nor change the default display characteristics.
