Yash Datta created SPARK-6471:
---------------------------------
Summary: Metastoreschema should only be a subset of parquetSchema to support
dropping of columns using replace columns
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.
