Thanks! Maybe what you point at is the resolved issue
https://issues.apache.org/jira/browse/SPARK-3851. Reading data from parquet
files with different but compatible schemas has been supported in Spark 1.3.0.

> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Reporter: Chaozhong Yang

> The original table's schema is like this:
> |-- a: string (nullable = true)
> |-- b: string (nullable = true)
> |-- c: string (nullable = true)
> |-- d: string (nullable = true)
> If we want to insert one row(can be transformed into DataFrame) with this
> schema:
> |-- a: string (nullable = true)
> |-- b: string (nullable = true)
> |-- c: string (nullable = true)
> Of course, that operation will fail. Actually, in many cases, people need to
> insert new rows with columns which is the subset of original table columns.
> If we can support and fix those issue, Spark SQL's insertion can be more
> valuable to users.
