[SPARK-17361][SQL] createExternalTable should fail if path is not given for file-based data source ## What changes were proposed in this pull request? Using the public `Catalog` API, users can create a file-based data source table, without giving the path options. For this case, currently we can create the table successfully, but fail when we read it. This is because when we create data source table, we resolve the data source relation without validating path: `resolveRelation(checkPathExist = false)`. `resolveRelation` is used to validate some arguments and infer schema and partitions, which is useless to managed table. So in this PR, we only resolve data source relation for external table, then we can remove the `checkPathExist` parameter in `DataSource.resolveRelation` and do some related cleanups. ## How was this patch tested? existing tests and new test in `CatalogSuite` You can merge this pull request into a Git repository by running: $ git pull https://github.com/cloud-fan/spark check-path Alternatively you can review and apply these changes as the patch at: https://github.com/apache/spark/pull/14921.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 #14921 ---- commit d53bf61ced6aa339c3e370dd2a320863ae6434c1 Author: Wenchen Fan <wenc...@databricks.com> Date: 2016-09-01T14:36:33Z createExternalTable should fail if path is not given for file-based data source ---- --- If your project is set up for it, you can reply to this email and have your reply appear on GitHub as well.
