Eric Maynard commented on SPARK-22436: -------------------------------------- [~asmaier] Wouldn't the right way to implement this be to use the existing function `regexp_replace`? I'm not sure why this needs to be a built-in function. Furthermore, if this was implemented, imo it should exist in all APIs, not just pyspark. > New function strip() to remove all whitespace from string > --------------------------------------------------------- > > Key: SPARK-22436 > URL: https://issues.apache.org/jira/browse/SPARK-22436 > Project: Spark > Issue Type: Improvement > Components: PySpark, Spark Core > Affects Versions: 2.2.0 > Reporter: Andreas Maier > Priority: Minor > Labels: features > > Since ticket SPARK-17299 the [trim() > function|https://spark.apache.org/docs/latest/api/python/pyspark.sql.html#pyspark.sql.functions.trim] > will not remove any whitespace characters from beginning and end of a string > but only spaces.
