Andreas Maier created SPARK-22436:
-------------------------------------
Summary: 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
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. This is correct in regard to the SQL standard, but it opens a
gap in functionality.
My suggestion is to add to the Spark API in analogy to pythons standard library
the functions l/r/strip(), which should remove all whitespace characters from a
string from beginning and/or end of a string respectively.
