Maxim Gekk updated SPARK-30892:
-------------------------------
Description: The spark.sql.variable.substitute.depth SQL config is not used
since Spark 2.4 inclusively. By the
[https://github.com/apache/spark/pull/27169], the config was placed to
SQLConf.removedSQLConfigs. And as a consequence of that when an user set it
non-default value (1 for example), he/she will get an exception. It is
acceptable for configs that could impact on the behavior but not for this
particular config. Raising of such exception will just make migration to Spark
3.0 more difficult. (was: The spark.sql.variable.substitute.depth SQL config
