[SPARK-19305][SQL] partitioned table should always put partition columns at the end of table schema ## What changes were proposed in this pull request? For data source tables, we will always reorder the specified table schema, or the query in CTAS, to put partition columns at the end. e.g. `CREATE TABLE t(a int, b int, c int, d int) USING parquet PARTITIONED BY (d, b)` will create a table with schema `<a, c, d, b>` Hive serde tables don't have this problem before, because its CREATE TABLE syntax specifies data schema and partition schema individually. However, after we unifed the CREATE TABLE syntax, Hive serde table also need to do the reorder. This PR puts the reorder logic in a analyzer rule, which works with both data source tables and Hive serde tables. ## How was this patch tested? new regression test You can merge this pull request into a Git repository by running: $ git pull https://github.com/cloud-fan/spark schema Alternatively you can review and apply these changes as the patch at: https://github.com/apache/spark/pull/16655.patch To close this pull request, make a commit to your master/trunk branch with (at least) the following in the commit message: This closes #16655 ---- commit 9ec7d36a198560441e3c3e96fa59789bdd36751b Author: Wenchen Fan <wenc...@databricks.com> Date: 2017-01-20T06:10:36Z partitioned table should always put partition columns at the end of table schema ---- --- If your project is set up for it, you can reply to this email and have your reply appear on GitHub as well.
