Support selecting from partitioned tabels with partitions having different data formats ## What changes were proposed in this pull request? (Please fill in changes proposed in this fix) Before these changes spark failed when selecting form a hive partitioned table with partitions with different data formats. Hive returned the correct results. We changed Spark to support the following SQL also: ALTER TABLE <table> SET FILEFORMAT PARQUET and ALTER TABLE <table> PARTITON <partitionspec> SET FILEFORMAT PARQUET ## How was this patch tested? (Please explain how this patch was tested. E.g. unit tests, integration tests, manual tests) (If this patch involves UI changes, please attach a screenshot; otherwise, remove this) Unittests are available in: org.apache.spark.sql.hive.execution.MultiFormatTableSuite Please review http://spark.apache.org/contributing.html before opening a pull request.
