> Key: SPARK-6471
> URL: https://issues.apache.org/jira/browse/SPARK-6471
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 1.3.0
> Reporter: Yash Datta
> Fix For: 1.4.0
>
>
> Currently in the parquet relation 2 implementation, error is thrown in case
> merged schema is not exactly the same as metastore schema.
> But to support cases like deletion of column using replace column command, we
> can relax the restriction so that even if metastore schema is a subset of
> merged parquet schema, the query will work.
