-------------------------------------
Summary: Add configuration parameter to adjust the numbers of
records and the charters per row before truncation when a user runs.show()
Key: SPARK-24442
URL: https://issues.apache.org/jira/browse/SPARK-24442
Project: Spark
Issue Type: Improvement
Components: Input/Output
Affects Versions: 2.3.0, 2.2.0
Reporter: Andrew K Long
Fix For: 2.4.0
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.
