[jira] [Created] (SPARK-12580) Remove string concatenations from usage and extended in @ExpressionDescription

Kazuaki Ishizaki created SPARK-12580:
----------------------------------------

             Summary: Remove string concatenations from usage and extended in @ExpressionDescription
                 Key: SPARK-12580
                 URL: https://issues.apache.org/jira/browse/SPARK-12580
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 2.0.0
            Reporter: Kazuaki Ishizaki
            Priority: Minor


More than one string concatenation in ``usage`` or ``extended`` for ``@ExpressinDescrption`` may cause compilation error.

We remove a string concatenation in these fields based on the following policy describe at https://github.com/apache/spark/pull/10488

Let's use multi-line string literals. If we have to have a line with more than 100 characters, let's use ``// scalastyle:off line.size.limit`` and ``// scalastyle:on line.size.limit`` to just bypass the line number requirement.
