Dan Monroe created SPARK-31628:
----------------------------------
Summary: Missing sql function, "replace".
Key: SPARK-31628
URL: https://issues.apache.org/jira/browse/SPARK-31628
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 2.4.4
Environment: Tested on v 2.4.4, spark-shell and in Scala Spark
application.
Reporter: Dan Monroe
In the spark sql functions docs, there is a function called
[replace|[https://spark.apache.org/docs/latest/api/sql/index.html#replace]]; a
non-regex string replace function that should have existed since 2.3.0.
In the spark-shell and in Scala Spark apps (2.4.4) I cannot find this function
inside of the `org.apache.spark.sql.functions` package, and it does not appear
to be defined in this file for these versions:
[https://github.com/apache/spark/blob/v2.3.0/sql/core/src/main/scala/org/apache/spark/sql/functions.scala]
[https://github.com/apache/spark/blob/v2.4.4/sql/core/src/main/scala/org/apache/spark/sql/functions.scala]
However, I can find it in the function registry:
[https://github.com/apache/spark/blob/v2.3.0/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/FunctionRegistry.scala#L338]
[https://github.com/apache/spark/blob/v2.4.4/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/FunctionRegistry.scala#L337]
It's not a huge deal because there is still "regexp_replace", it's just a
little misleading.
