Michael Armbrust commented on SPARK-22824:
------------------------------------------

This is technically an internal API (as is all of 
[org.apache.spark.sql.execution|https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/package.scala]).
  That said, I think we should do our best to preserve compatibility until 
there is a {{@Stable}} public alternative (which is the goal of the V2 project).

We'll open a PR to try and fix this.

> This broke our custom sources that are called in Spark jobs running on Azure 
> Databricks 3.4 since the Maven package does not match the hosted Spark bits. 
> We use the following Maven version to be able to deploy on Azure Databricks:
>         <dependency>
>             <groupId>org.apache.spark</groupId>
>             <artifactId>spark-sql_2.11</artifactId>
