* [SPARK-18885][SQL] unify CREATE TABLE syntax for data source and hive serde ↵Wenchen Fan2017-01-054-4/+4
| | | | | | | | | | | | | | | | | | | | | | | tables ## What changes were proposed in this pull request? Today we have different syntax to create data source or hive serde tables, we should unify them to not confuse users and step forward to make hive a data source. Please read https://issues.apache.org/jira/secure/attachment/12843835/CREATE-TABLE.pdf for details. TODO(for follow-up PRs): 1. TBLPROPERTIES is not added to the new syntax, we should decide if we wanna add it later. 2. `SHOW CREATE TABLE` should be updated to use the new syntax. 3. we should decide if we wanna change the behavior of `SET LOCATION`. ## How was this patch tested? new tests Author: Wenchen Fan <wenchen@databricks.com> Closes #16296 from cloud-fan/create-table.

* Fix example of tf_idf with minDocFreqMaxime Rihouey2016-10-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? The python example for tf_idf with the parameter "minDocFreq" is not properly set up because the same variable is used to transform the document for both with and without the "minDocFreq" parameter. The IDF(minDocFreq=2) is stored in the variable "idfIgnore" but then it is the original variable "idf" used to transform the "tf" instead of the "idfIgnore". ## How was this patch tested? Before the results for "tfidf" and "tfidfIgnore" were the same: tfidf: (1048576,[1046921],[3.75828890549]) (1048576,[1046920],[3.75828890549]) (1048576,[1046923],[3.75828890549]) (1048576,[892732],[3.75828890549]) (1048576,[892733],[3.75828890549]) (1048576,[892734],[3.75828890549]) tfidfIgnore: (1048576,[1046921],[3.75828890549]) (1048576,[1046920],[3.75828890549]) (1048576,[1046923],[3.75828890549]) (1048576,[892732],[3.75828890549]) (1048576,[892733],[3.75828890549]) (1048576,[892734],[3.75828890549]) After the fix those are how they should be: tfidf: (1048576,[1046921],[3.75828890549]) (1048576,[1046920],[3.75828890549]) (1048576,[1046923],[3.75828890549]) (1048576,[892732],[3.75828890549]) (1048576,[892733],[3.75828890549]) (1048576,[892734],[3.75828890549]) tfidfIgnore: (1048576,[1046921],[0.0]) (1048576,[1046920],[0.0]) (1048576,[1046923],[0.0]) (1048576,[892732],[0.0]) (1048576,[892733],[0.0]) (1048576,[892734],[0.0]) Author: Maxime Rihouey <maxime.rihouey@gmail.com> Closes #15503 from maximerihouey/patch-1.
* [SPARK-17338][SQL] add global temp viewWenchen Fan2016-10-103-2/+78
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? Global temporary view is a cross-session temporary view, which means it's shared among all sessions. Its lifetime is the lifetime of the Spark application, i.e. it will be automatically dropped when the application terminates. It's tied to a system preserved database `global_temp`(configurable via SparkConf), and we must use the qualified name to refer a global temp view, e.g. SELECT * FROM global_temp.view1. changes for `SessionCatalog`: 1. add a new field `gloabalTempViews: GlobalTempViewManager`, to access the shared global temp views, and the global temp db name. 2. `createDatabase` will fail if users wanna create `global_temp`, which is system preserved. 3. `setCurrentDatabase` will fail if users wanna set `global_temp`, which is system preserved. 4. add `createGlobalTempView`, which is used in `CreateViewCommand` to create global temp views. 5. add `dropGlobalTempView`, which is used in `CatalogImpl` to drop global temp view. 6. add `alterTempViewDefinition`, which is used in `AlterViewAsCommand` to update the view definition for local/global temp views. 7. `renameTable`/`dropTable`/`isTemporaryTable`/`lookupRelation`/`getTempViewOrPermanentTableMetadata`/`refreshTable` will handle global temp views. changes for SQL commands: 1. `CreateViewCommand`/`AlterViewAsCommand` is updated to support global temp views 2. `ShowTablesCommand` outputs a new column `database`, which is used to distinguish global and local temp views. 3. other commands can also handle global temp views if they call `SessionCatalog` APIs which accepts global temp views, e.g. `DropTableCommand`, `AlterTableRenameCommand`, `ShowColumnsCommand`, etc. changes for other public API 1. add a new method `dropGlobalTempView` in `Catalog` 2. `Catalog.findTable` can find global temp view 3. add a new method `createGlobalTempView` in `Dataset` ## How was this patch tested? new tests in `SQLViewSuite` Author: Wenchen Fan <wenchen@databricks.com> Closes #14897 from cloud-fan/global-temp-view.

This change modifies the implementation of DataFrameWriter.save such that it works with jdbc, and the call to jdbc merely delegates to save. ## How was this patch tested? This was tested via unit tests in the JDBCWriteSuite, of which I added one new test to cover this scenario. ## Additional details rxin This seems to have been most recently touched by you and was also commented on in the JIRA.

| | | | | | | | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? As Spark 2.0.1 will be released soon (mentioned in the spark dev mailing list), besides the critical bugs, it's better to fix the code style errors before the release. Before: ``` ./dev/lint-java Checkstyle checks failed at following occurrences: [ERROR] src/main/java/org/apache/spark/util/collection/unsafe/sort/UnsafeExternalSorter.java:[525] (sizes) LineLength: Line is longer than 100 characters (found 119).

| | | | | | | | | | | | | | | | | | | | | | | | | | | indentation in documentation ## What changes were proposed in this pull request? Originally this PR was based on #14491 but I realised that fixing examples are more sensible rather than comments. This PR fixes three things below: - Fix two wrong examples in `structured-streaming-programming-guide.md`. Loading via `read.load(..)` without `as` will be `Dataset<Row>` not `Dataset<String>` in Java. - Fix indentation across `structured-streaming-programming-guide.md`. Python has 4 spaces and Scala and Java have double spaces. These are inconsistent across the examples. - Fix `StructuredNetworkWordCountWindowed` and `StructuredNetworkWordCount` in Java and Scala to initially load `DataFrame` and `Dataset<Row>` to be consistent with the comments and some examples in `structured-streaming-programming-guide.md` and to match Scala and Java to Python one (Python one loads it as `DataFrame` initially). ## How was this patch tested?

This mostly consisted of modifying what was printed at the end of the example, such as calling show() with truncate=False, but sometimes required minor tweaks in the example data to get relevant output. Explicitly set parameters when they are used as part of the example. Fixed Java examples that failed to run because of using old-style MLlib Vectors or problem with schema.
