------------------------------------
Summary: The Signature for ConcatWs in Spark SQL Docs Is
Inconsistent with the Actual Behavior
Key: SPARK-34268
URL: https://issues.apache.org/jira/browse/SPARK-34268
Project: Spark
Issue Type: Bug
Components: docs
Affects Versions: 3.2.0
Reporter: Yuning Zhang
In https://spark.apache.org/docs/latest/api/sql/index.html#concat_ws, the
signature of conccat_ws is concat_ws(sep, [str | array(str)]+). However, it
doesn't actually need any str or array(str) arguments. Only having the sep
argument seems to work.
For example, select concat_ws("a") returns an empty string.
scala> sql("""select concat_ws("a")""").show
+------------+
|concat_ws(a)|
+------------+
| |
+------------+
