[SPARK-9381] [SQL] Migrate JSON data source to the new partitioning data source Support partitioning for the JSON data source. Still 2 open issues for the `HadoopFsRelation` - `refresh()` will invoke the `discoveryPartition()`, which will auto infer the data type for the partition columns, and maybe conflict with the given partition columns. (TODO enable `HadoopFsRelationSuite.Partition column type casting" - When insert data into a cached HadoopFsRelation based table, we need to invalidate the cache after the insertion (TODO enable `InsertSuite.Caching`) Author: Cheng Hao <hao.ch...@intel.com> Closes #7696 from chenghao-intel/json and squashes the following commits: d90b104 [Cheng Hao] revert the change for JacksonGenerator.apply 307111d [Cheng Hao] fix bug in the unit test 8738c8a [Cheng Hao] fix bug in unit testing 35f2cde [Cheng Hao] support partition for json format (cherry picked from commit 519cf6d3f764a977770266784d6902fe205a070f) Signed-off-by: Reynold Xin <r...@databricks.com> Project: http://git-wip-us.apache.org/repos/asf/spark/repo Commit: http://git-wip-us.apache.org/repos/asf/spark/commit/3d247672 Tree: http://git-wip-us.apache.org/repos/asf/spark/tree/3d247672 Diff: http://git-wip-us.apache.org/repos/asf/spark/diff/3d247672 Branch: refs/heads/branch-1.5 Commit: 3d247672b84b7476a3e95bc6511b4327e5843e71 Parents: d5f7881 Author: Cheng Hao <hao.ch...@intel.com> Authored: Wed Aug 5 22:35:55 2015 +0800 Committer: Reynold Xin <r...@databricks.com> Committed: Thu Aug 6 13:21:04 2015 -0700 ---------------------------------------------------------------------- .../scala/org/apache/spark/sql/DataFrame.scala | 2 -
