* [MINOR] [SPARKR] Update data-manipulation.R to use native csv readerYanbo Liang2016-05-091-4/+3
| | | | | | | | | | | | | ## What changes were proposed in this pull request? * Since Spark has supported native csv reader, it does not necessary to use the third party ```spark-csv``` in ```examples/src/main/r/data-manipulation.R```. Meanwhile, remove all ```spark-csv``` usage in SparkR. * Running R applications through ```sparkR``` is not supported as of Spark 2.0, so we change to use ```./bin/spark-submit``` to run the example. ## How was this patch tested? Offline test. Author: Yanbo Liang <ybliang8@gmail.com> Closes #13005 from yanboliang/r-df-examples.

| | | | | | | | | | | | | | | | | inconsistent with java and python ## What changes were proposed in this pull request? In spark.ml document, the LogisticRegression scala example uses sqlCtx. It is inconsistent with java and python examples which use sqlContext. In addition, a user can't copy & paste to run the example in spark-shell as sqlCtx doesn't exist in spark-shell while sqlContext exists.

| | | | | | | | | | are flattened Spark's published POMs are supposed to be flattened and not contain variable substitution (see SPARK-3812), but the dummy dependency that was required for this was accidentally removed. We should re-introduce this dependency in order to fix an issue where the un-flattened POMs cause the wrong dependencies to be included in Scala 2.10 published POMs. Author: Josh Rosen <joshrosen@databricks.com> Closes #12706 from JoshRosen/SPARK-14925-published-poms-should-be-flattened.

| | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? This removes the class `HiveContext` itself along with all code usages associated with it. The bulk of the work was already done in #12485. This is mainly just code cleanup and actually removing the class. Note: A couple of things will break after this patch. These will be fixed separately. - the python HiveContext - all the documentation / comments referencing HiveContext - there will be no more HiveContext in the REPL (fixed by #12589) ## How was this patch tested? No change in functionality. Author: Andrew Or <andrew@databricks.com> Closes #12585 from andrewor14/delete-hive-context.
* [SPARK-14744][EXAMPLES] Clean up examples packaging, remove outdated examples.Marcelo Vanzin2016-04-2510-1118/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | First, make all dependencies in the examples module provided, and explicitly list a couple of ones that somehow are promoted to compile by maven. This means that to run streaming examples, the streaming connector package needs to be provided to run-examples using --packages or --jars, just like regular apps. Also, remove a couple of outdated examples. HBase has had Spark bindings for a while and is even including them in the HBase distribution in the next version, making the examples obsolete. The same applies to Cassandra, which seems to have a proper Spark binding library already. I just tested the build, which passes, and ran SparkPi. The examples jars directory now has only two jars: ``` $ ls -1 examples/target/scala-2.11/jars/ scopt_2.11-3.3.0.jar spark-examples_2.11-2.0.0-SNAPSHOT.jar ``` Author: Marcelo Vanzin <vanzin@cloudera.com> Closes #12544 from vanzin/SPARK-14744.
* [SPARK-14883][DOCS] Fix wrong R examples and make them up-to-dateDongjoon Hyun2016-04-242-12/+12
| | | | | | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? This issue aims to fix some errors in R examples and make them up-to-date in docs and example modules. - Remove the wrong usage of `map`. We need to use `lapply` in `sparkR` if needed. However, `lapply` is private so far. The corrected example will be added later. - Fix the wrong example in Section `Generic Load/Save Functions` of `docs/sql-programming-guide.md` for consistency - Fix datatypes in `sparkr.md`. - Update a data result in `sparkr.md`. - Replace deprecated functions to remove warnings: jsonFile -> read.json, parquetFile -> read.parquet - Use up-to-date R-like functions: loadDF -> read.df, saveDF -> write.df, saveAsParquetFile -> write.parquet - Replace `SparkR DataFrame` with `SparkDataFrame` in `dataframe.R` and `data-manipulation.R`. - Other minor syntax fixes and a typo. ## How was this patch tested? Manual. Author: Dongjoon Hyun <dongjoon@apache.org> Closes #12649 from dongjoon-hyun/SPARK-14883.

| | | | | | | | | | | | | | | | non-declared InterruptedException ## What changes were proposed in this pull request? `JavaStreamingContext.awaitTermination` methods should be declared as `throws[InterruptedException]` so that this exception can be handled in Java code. Note this is not just a doc change, but an API change, since now (in Java) the method has a checked exception to handle. All await-like methods in Java APIs behave this way, so seems worthwhile for 2.0. ## How was this patch tested?

This PR doesn't change the output type. In Java, `Dataset[_]` maps to `Dataset<?>`, which includes `Dataset<Row>`. Some implementations were changed in order to return `DataFrame`.

| | | | | | | | | | | | | | | | | | | | This change modifies the "assembly/" module to just copy needed dependencies to its build directory, and modifies the packaging script to pick those up (and remove duplicate jars packages in the examples module). I also made some minor adjustments to dependencies to remove some test jars from the final packaging, and remove jars that conflict with each other when packaged separately (e.g. servlet api). Also note that this change restores guava in applications' classpaths, even though it's still shaded inside Spark.

* [SPARK-13017][DOCS] Replace example code in mllib-feature-extraction.md ↵Xin Ren2016-03-2414-0/+847
| | | | | | | | | | | | | | | | | | | | | using include_example Replace example code in mllib-feature-extraction.md using include_example https://issues.apache.org/jira/browse/SPARK-13017 The example code in the user guide is embedded in the markdown and hence it is not easy to test. It would be nice to automatically test them. This JIRA is to discuss options to automate example code testing and see what we can do in Spark 1.6. Goal is to move actual example code to spark/examples and test compilation in Jenkins builds. Then in the markdown, we can reference part of the code to show in the user guide. This requires adding a Jekyll tag that is similar to https://github.com/jekyll/jekyll/blob/master/lib/jekyll/tags/include.rb, e.g., called include_example. `{% include_example scala/org/apache/spark/examples/mllib/TFIDFExample.scala %}` Jekyll will find `examples/src/main/scala/org/apache/spark/examples/mllib/TFIDFExample.scala` and pick code blocks marked "example" and replace code block in `{% highlight %}` in the markdown. See more sub-tasks in parent ticket: https://issues.apache.org/jira/browse/SPARK-11337 Author: Xin Ren <iamshrek@126.com> Closes #11142 from keypointt/SPARK-13017.
* [SPARK-13019][DOCS] fix for scala-2.10 build: Replace example code in ↵Xin Ren2016-03-2418-0/+1020
| | | | | | | | | | | | | | | | | | | | | | mllib-statistics.md using include_example ## What changes were proposed in this pull request? This PR for ticket SPARK-13019 is based on previous PR(https://github.com/apache/spark/pull/11108). Since PR(https://github.com/apache/spark/pull/11108) is breaking scala-2.10 build, more work is needed to fix build errors. What I did new in this PR is adding keyword argument for 'fractions': ` val approxSample = data.sampleByKey(withReplacement = false, fractions = fractions)` ` val exactSample = data.sampleByKeyExact(withReplacement = false, fractions = fractions)` I reopened ticket on JIRA but sorry I don't know how to reopen a GitHub pull request, so I just submitting a new pull request. ## How was this patch tested? Manual build testing on local machine, build based on scala-2.10. Author: Xin Ren <iamshrek@126.com> Closes #11901 from keypointt/SPARK-13019.
