PR: https://github.com/apache/spark/pull/21893
> Spark SQL fails when reading a partitioned hive table with different formats
> per partition
> ------------------------------------------------------------------------------------------
>
> Key: SPARK-24965
> URL: https://issues.apache.org/jira/browse/SPARK-24965
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.3.1
> Reporter: Kris Geusebroek
> Priority: Major
> Labels: pull-request-available
>
> When a hive parquet partitioned table contains a partition with a different
> format (avro for example) the select * fails with a read exception (avro file
> is not a parquet file)
> Selecting in hive acts as expected.
> To support this a new sql syntax needed to be supported also:
> * ALTER TABLE <tbl> <partiitonspec?> SET FILEFORMAT <format>
> This is included in the same PR since the unittest needs this to setup the
> testdata.
