* [SPARK-12091] [PYSPARK] Deprecate the JAVA-specific deserialized storage levelsgatorsmile2015-12-181-3/+3
| | | | | | | | | | | | | | The current default storage level of Python persist API is MEMORY_ONLY_SER. This is different from the default level MEMORY_ONLY in the official document and RDD APIs. davies Is this inconsistency intentional? Thanks! Updates: Since the data is always serialized on the Python side, the storage levels of JAVA-specific deserialization are not removed, such as MEMORY_ONLY. Updates: Based on the reviewers' feedback. In Python, stored objects will always be serialized with the [Pickle](https://docs.python.org/2/library/pickle.html) library, so it does not matter whether you choose a serialized level. The available storage levels in Python include `MEMORY_ONLY`, `MEMORY_ONLY_2`, `MEMORY_AND_DISK`, `MEMORY_AND_DISK_2`, `DISK_ONLY`, `DISK_ONLY_2` and `OFF_HEAP`. Author: gatorsmile <gatorsmile@gmail.com> Closes #10092 from gatorsmile/persistStorageLevel.

* [SPARK-12012][SQL] Show more comprehensive PhysicalRDD metadata when ↵Cheng Lian2015-12-091-1/+1
| | | | | | | | | | | | | | | | visualizing SQL query plan This PR adds a `private[sql]` method `metadata` to `SparkPlan`, which can be used to describe detail information about a physical plan during visualization. Specifically, this PR uses this method to provide details of `PhysicalRDD`s translated from a data source relation. For example, a `ParquetRelation` converted from Hive metastore table `default.psrc` is now shown as the following screenshot: ![image](https://cloud.githubusercontent.com/assets/230655/11526657/e10cb7e6-9916-11e5-9afa-f108932ec890.png) And here is the screenshot for a regular `ParquetRelation` (not converted from Hive metastore table) loaded from a really long path: ![output](https://cloud.githubusercontent.com/assets/230655/11680582/37c66460-9e94-11e5-8f50-842db5309d5a.png) Author: Cheng Lian <lian@databricks.com> Closes #10004 from liancheng/spark-12012.physical-rdd-metadata.

| | | | | | | | | | | | | | | | | | | | | | | | This patch adds the following options to the JSON data source, for dealing with non-standard JSON files: * `allowComments` (default `false`): ignores Java/C++ style comment in JSON records * `allowUnquotedFieldNames` (default `false`): allows unquoted JSON field names * `allowSingleQuotes` (default `true`): allows single quotes in addition to double quotes * `allowNumericLeadingZeros` (default `false`): allows leading zeros in numbers (e.g. 00012) To avoid passing a lot of options throughout the json package, I introduced a new JSONOptions case class to define all JSON config options. Also updated documentation to explain these options.

| | | | | | | | | | | | | | provided schema When creating a DataFrame from an RDD in PySpark, `createDataFrame` calls `.take(10)` to verify the first 10 rows of the RDD match the provided schema. Similar to https://issues.apache.org/jira/browse/SPARK-8070, but that issue affected cases where a schema was not provided. Verifying the first 10 rows is of limited utility and causes the DAG to be executed non-lazily. If necessary, I believe this verification should be done lazily on all rows. However, since the caller is providing a schema to follow, I think it's acceptable to simply fail if the schema is incorrect. marmbrus We chatted about this at SparkSummitEU. davies you made a similar change for the infer-schema path in https://github.com/apache/spark/pull/6606 Author: Jason White <jason.white@shopify.com> Closes #9392 from JasonMWhite/createDataFrame_without_take.
