Michael, please, see http://apache-spark-user-list.1001560.n3.nabble.com/Schema-evolution-in-tables-tt23999.html
The exception is java.lang.RuntimeException: Relation[ ... ] org.apache.spark.sql.parquet.ParquetRelation2@83a73a05 requires that the query in the SELECT clause of the INSERT INTO/OVERWRITE statement generates the same number of columns as its schema. Is this behavior expected? Shall I create a JIRA issue if it is not?

It would also be awesome if you could try with Spark 1.5 when the first preview comes out (hopefully early next week).

Must the Hive tables be set up as external tables outside of saveAsTable? In my experience, in 1.4.1, writing to a table with SaveMode.Append fails if the schema don't match.

However, Spark 1.4+ should.
