[SPARK-15143][SPARK-15144][SQL] Add CSV tests with HadoopFsRelationTest and support for nullValue for other types ## What changes were proposed in this pull request? Currently, `nullValue` option does not work for some types, `BooleanType`, `TimestampType`, `DateType` and `StringType`. So, currently there is no way to read null for those types. This PR adds the support just like the other types. Also, CSV data source is not being tested with `HadoopFsRelationTest` as a `HadoopFsRelation`. `HadoopFsRelationTest` includes 50 more tests (eg. partitioned table tests). This PR adds two variables, `extraReadOptions` and `extraWriteOptions` in `HadoopFsRelationTest` so that the child class gives some options for reading and writing. In order to get the tests in `HadoopFsRelationTest` passed, CSV data source needs to give options `header` and `inferSchema` as `true` for reading and `header` as `true` for writing. ## How was this patch tested? Unittests in `CSVHadoopFsRelationTest` and edited tests in `CSVSuite` You can merge this pull request into a Git repository by running: $ git pull https://github.com/HyukjinKwon/spark SPARK-15143-15144 Alternatively you can review and apply these changes as the patch at: https://github.com/apache/spark/pull/12921.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 #12921 ---- commit ef71599130291aa6bb684afb47e88307b38238f1 Author: hyukjinkwon <gurwls...@gmail.com> Date: 2016-05-05T05:47:07Z Add CSV tests with HadoopFsRelationTest and support for nullValue for other types ---- --- If your project is set up for it, you can reply to this email and have your reply appear on GitHub as well.
