* [SPARK-15412][PYSPARK][SPARKR][DOCS] Improve linear isotonic regression ↵Holden Karau2016-05-241-13/+17
| | | | | | | | | | | | | | | | | | pydoc & doc build insturctions ## What changes were proposed in this pull request? PySpark: Add links to the predictors from the models in regression.py, improve linear and isotonic pydoc in minor ways. User guide / R: Switch the installed package list to be enough to build the R docs on a "fresh" install on ubuntu and add sudo to match the rest of the commands. User Guide: Add a note about using gem2.0 for systems with both 1.9 and 2.0 (e.g. some ubuntu but maybe more). ## How was this patch tested? built pydocs locally, tested new user build instructions Author: Holden Karau <holden@us.ibm.com> Closes #13199 from holdenk/SPARK-15412-improve-linear-isotonic-regression-pydoc.
* [SPARK-15433] [PYSPARK] PySpark core test should not use SerDe from ↵Liang-Chi Hsieh2016-05-241-2/+2
| | | | | | | | | | | | | | | PythonMLLibAPI ## What changes were proposed in this pull request? Currently PySpark core test uses the `SerDe` from `PythonMLLibAPI` which includes many MLlib things. It should use `SerDeUtil` instead. ## How was this patch tested? Existing tests. Author: Liang-Chi Hsieh <simonh@tw.ibm.com> Closes #13214 from viirya/pycore-use-serdeutil.
* [SPARK-11753][SQL][TEST-HADOOP2.2] Make allowNonNumericNumbers option workLiang-Chi Hsieh2016-05-241-0/+3
| | | | | | | | | | | | | | | ## What changes were proposed in this pull request? Jackson suppprts `allowNonNumericNumbers` option to parse non-standard non-numeric numbers such as "NaN", "Infinity", "INF". Currently used Jackson version (2.5.3) doesn't support it all. This patch upgrades the library and make the two ignored tests in `JsonParsingOptionsSuite` passed. ## How was this patch tested? `JsonParsingOptionsSuite`. Author: Liang-Chi Hsieh <simonh@tw.ibm.com> Author: Liang-Chi Hsieh <viirya@appier.com> Closes #9759 from viirya/fix-json-nonnumric.
* [SPARK-15442][ML][PYSPARK] Add 'relativeError' param to PySpark ↵Nick Pentreath2016-05-241-15/+36
| | | | | | | | | | | | | | | | | | QuantileDiscretizer This PR adds the `relativeError` param to PySpark's `QuantileDiscretizer` to match Scala. Also cleaned up a duplication of `numBuckets` where the param is both a class and instance attribute (I removed the instance attr to match the style of params throughout `ml`). Finally, cleaned up the docs for `QuantileDiscretizer` to reflect that it now uses `approxQuantile`. ## How was this patch tested? A little doctest and built API docs locally to check HTML doc generation. Author: Nick Pentreath <nickp@za.ibm.com> Closes #13228 from MLnick/SPARK-15442-py-relerror-param.
* [SPARK-15397][SQL] fix string udf locate as hiveDaoyuan Wang2016-05-231-1/+1
| | | | | | | | | | | | | | ## What changes were proposed in this pull request? in hive, `locate("aa", "aaa", 0)` would yield 0, `locate("aa", "aaa", 1)` would yield 1 and `locate("aa", "aaa", 2)` would yield 2, while in Spark, `locate("aa", "aaa", 0)` would yield 1, `locate("aa", "aaa", 1)` would yield 2 and `locate("aa", "aaa", 2)` would yield 0. This results from the different understanding of the third parameter in udf `locate`. It means the starting index and starts from 1, so when we use 0, the return would always be 0. ## How was this patch tested? tested with modified `StringExpressionsSuite` and `StringFunctionsSuite` Author: Daoyuan Wang <daoyuan.wang@intel.com> Closes #13186 from adrian-wang/locate.

* [MINOR][SQL][DOCS] Add notes of the deterministic assumption on UDF functionsDongjoon Hyun2016-05-231-0/+3
| | | | | | | | | | | | | | ## What changes were proposed in this pull request? Spark assumes that UDF functions are deterministic. This PR adds explicit notes about that. ## How was this patch tested? It's only about docs. Author: Dongjoon Hyun <dongjoon@apache.org> Closes #13087 from dongjoon-hyun/SPARK-15282.
* [SPARK-15456][PYSPARK] Fixed PySpark shell context initialization when ↵Bryan Cutler2016-05-201-2/+2
| | | | | | | | | | | | | | | | HiveConf not present ## What changes were proposed in this pull request? When PySpark shell cannot find HiveConf, it will fallback to create a SparkSession from a SparkContext. This fixes a bug caused by using a variable to SparkContext before it was initialized. ## How was this patch tested? Manually starting PySpark shell and using the SparkContext Author: Bryan Cutler <cutlerb@gmail.com> Closes #13237 from BryanCutler/pyspark-shell-session-context-SPARK-15456.
* [SPARK-15444][PYSPARK][ML][HOTFIX] Default value mismatch of param ↵Liang-Chi Hsieh2016-05-201-6/+5
| | | | | | | | | | | | | | | linkPredictionCol for GeneralizedLinearRegression ## What changes were proposed in this pull request? Default value mismatch of param linkPredictionCol for GeneralizedLinearRegression between PySpark and Scala. That is because default value conflict between #13106 and #13129. This causes ml.tests failed. ## How was this patch tested? Existing tests. Author: Liang-Chi Hsieh <simonh@tw.ibm.com> Closes #13220 from viirya/hotfix-regresstion.
* [SPARK-15417][SQL][PYTHON] PySpark shell always uses in-memory catalogAndrew Or2016-05-192-3/+11
| | | | | | | | | | | | | | ## What changes were proposed in this pull request? There is no way to use the Hive catalog in `pyspark-shell`. This is because we used to create a `SparkContext` before calling `SparkSession.enableHiveSupport().getOrCreate()`, which just gets the existing `SparkContext` instead of creating a new one. As a result, `spark.sql.catalogImplementation` was never propagated. ## How was this patch tested? Manual. Author: Andrew Or <andrew@databricks.com> Closes #13203 from andrewor14/fix-pyspark-shell.
* [SPARK-15075][SPARK-15345][SQL] Clean up SparkSession builder and propagate ↵Reynold Xin2016-05-192-4/+18
| | | | | | | | | | | | | | | | config options to existing sessions if specified ## What changes were proposed in this pull request? Currently SparkSession.Builder use SQLContext.getOrCreate. It should probably the the other way around, i.e. all the core logic goes in SparkSession, and SQLContext just calls that. This patch does that. This patch also makes sure config options specified in the builder are propagated to the existing (and of course the new) SparkSession. ## How was this patch tested? Updated tests to reflect the change, and also introduced a new SparkSessionBuilderSuite that should cover all the branches. Author: Reynold Xin <rxin@databricks.com> Closes #13200 from rxin/SPARK-15075.

* [SPARK-15392][SQL] fix default value of size estimation of logical planDavies Liu2016-05-191-1/+1
| | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? We use autoBroadcastJoinThreshold + 1L as the default value of size estimation, that is not good in 2.0, because we will calculate the size based on size of schema, then the estimation could be less than autoBroadcastJoinThreshold if you have an SELECT on top of an DataFrame created from RDD. This PR change the default value to Long.MaxValue. ## How was this patch tested? Added regression tests. Author: Davies Liu <davies@databricks.com> Closes #13183 from davies/fix_default_size.

* [SPARK-14891][ML] Add schema validation for ALSNick Pentreath2016-05-181-4/+4
| | | | | | | | | | | | | This PR adds schema validation to `ml`'s ALS and ALSModel. Currently, no schema validation was performed as `transformSchema` was never called in `ALS.fit` or `ALSModel.transform`. Furthermore, due to no schema validation, if users passed in Long (or Float etc) ids, they would be silently cast to Int with no warning or error thrown. With this PR, ALS now supports all numeric types for `user`, `item`, and `rating` columns. The rating column is cast to `Float` and the user and item cols are cast to `Int` (as is the case currently) - however for user/item, the cast throws an error if the value is outside integer range. Behavior for rating col is unchanged (as it is not an issue). ## How was this patch tested? New test cases in `ALSSuite`. Author: Nick Pentreath <nickp@za.ibm.com> Closes #12762 from MLnick/SPARK-14891-als-validate-schema.

The PySpark SQL `test_column_name_with_non_ascii` wants to test non-ascii column name. But it doesn't actually test it. We need to construct an unicode explicitly using `unicode` under Python 2. ## How was this patch tested? Existing tests.

* [SPARK-15244] [PYTHON] Type of column name created with createDataFrame is ↵Dongjoon Hyun2016-05-172-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | not consistent. ## What changes were proposed in this pull request? **createDataFrame** returns inconsistent types for column names. ```python >>> from pyspark.sql.types import StructType, StructField, StringType >>> schema = StructType([StructField(u"col", StringType())]) >>> df1 = spark.createDataFrame([("a",)], schema) >>> df1.columns # "col" is str ['col'] >>> df2 = spark.createDataFrame([("a",)], [u"col"]) >>> df2.columns # "col" is unicode [u'col'] ``` The reason is only **StructField** has the following code. ``` if not isinstance(name, str): name = name.encode('utf-8') ``` This PR adds the same logic into **createDataFrame** for consistency. ``` if isinstance(schema, list): schema = [x.encode('utf-8') if not isinstance(x, str) else x for x in schema] ``` ## How was this patch tested?

* [SPARK-15264][SPARK-15274][SQL] CSV Reader Error on Blank Column NamesBill Chambers2016-05-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? When a CSV begins with: - `,,` OR - `"","",` meaning that the first column names are either empty or blank strings and `header` is specified to be `true`, then the column name is replaced with `C` + the index number of that given column. For example, if you were to read in the CSV: ``` "","second column" "hello", "there" ``` Then column names would become `"C0", "second column"`. This behavior aligns with what currently happens when `header` is specified to be `false` in recent versions of Spark. ### Current Behavior in Spark <=1.6 In Spark <=1.6, a CSV with a blank column name becomes a blank string, `""`, meaning that this column cannot be accessed. However the CSV reads in without issue. ### Current Behavior in Spark 2.0 Spark throws a NullPointerError and will not read in the file. #### Reproduction in 2.0 https://databricks-prod-cloudfront.cloud.databricks.com/public/4027ec902e239c93eaaa8714f173bcfc/346304/2828750690305044/484361/latest.html ## How was this patch tested? A new test was added to `CSVSuite` to account for this issue. We then have asserts that test for being able to select both the empty column names as well as the regular column names.

* [SPARK-14936][BUILD][TESTS] FlumePollingStreamSuite is slowXin Ren2016-05-101-1/+1
| | | | | | | | | | | | | | | | | | | | https://issues.apache.org/jira/browse/SPARK-14936 ## What changes were proposed in this pull request? FlumePollingStreamSuite contains two tests which run for a minute each. This seems excessively slow and we should speed it up if possible. In this PR, instead of creating `StreamingContext` directly from `conf`, here an underlying `SparkContext` is created before all and it is used to create each`StreamingContext`. Running time is reduced by avoiding multiple `SparkContext` creations and destroys. ## How was this patch tested? Tested on my local machine running `testOnly *.FlumePollingStreamSuite` Author: Xin Ren <iamshrek@126.com> Closes #12845 from keypointt/SPARK-14936.

* [SPARK-14603][SQL] Verification of Metadata Operations by Session Cataloggatorsmile2016-05-101-0/+2
| | | | | | | | | | | | | | | | | | Since we cannot really trust if the underlying external catalog can throw exceptions when there is an invalid metadata operation, let's do it in SessionCatalog. - [X] The first step is to unify the error messages issued in Hive-specific Session Catalog and general Session Catalog. - [X] The second step is to verify the inputs of metadata operations for partitioning-related operations. This is moved to a separate PR: https://github.com/apache/spark/pull/12801 - [X] The third step is to add database existence verification in `SessionCatalog` - [X] The fourth step is to add table existence verification in `SessionCatalog` - [X] The fifth step is to add function existence verification in `SessionCatalog` Add test cases and verify the error messages we issued Author: gatorsmile <gatorsmile@gmail.com> Author: xiaoli <lixiao1983@gmail.com> Author: Xiao Li <xiaoli@Xiaos-MacBook-Pro.local> Closes #12385 from gatorsmile/verifySessionAPIs.
