(Please fill in changes proposed in this fix) In this DataFrame example, we use VectorImplicits._, which is private API. Since Vectors object has public API, we use Vectors.fromML instead of implicts. ## How was this patch tested? (Please explain how this patch was tested.

* [SPARK-15031][EXAMPLES][FOLLOW-UP] Make Python param example working with ↵hyukjinkwon2016-05-193-15/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | SparkSession ## What changes were proposed in this pull request? It seems most of Python examples were changed to use SparkSession by https://github.com/apache/spark/pull/12809. This PR said both examples below: - `simple_params_example.py` - `aft_survival_regression.py` are not changed because it dose not work. It seems `aft_survival_regression.py` is changed by https://github.com/apache/spark/pull/13050 but `simple_params_example.py` is not yet. This PR corrects the example and make this use SparkSession. In more detail, it seems `threshold` is replaced to `thresholds` here and there by https://github.com/apache/spark/commit/5a23213c148bfe362514f9c71f5273ebda0a848a. However, when it calls `lr.fit(training, paramMap)` this overwrites the values. So, `threshold` was 5 and `thresholds` becomes 5.5 (by `1 / (1 + thresholds(0) / thresholds(1)`). According to the comment below. this is not allowed, https://github.com/apache/spark/blob/354f8f11bd4b20fa99bd67a98da3525fd3d75c81/mllib/src/main/scala/org/apache/spark/ml/classification/LogisticRegression.scala#L58-L61. So, in this PR, it sets the equivalent value so that this does not throw an exception. ## How was this patch tested? Manully (`mvn package -DskipTests && spark-submit simple_params_example.py`) Author: hyukjinkwon <gurwls223@gmail.com> Closes #13135 from HyukjinKwon/SPARK-15031.

(Please fill in changes proposed in this fix) copy & paste example in ml-collaborative-filtering.html into spark-shell, we see the following errors. scala> case class Rating(userId: Int, movieId: Int, rating: Float, timestamp: Long) defined class Rating scala> object Rating { def parseRating(str: String): Rating = { | val fields = str.split("::") | assert(fields.size == 4) | Rating(fields(0).toInt, fields(1).toInt, fields(2).toFloat, fields(3).toLong) | } } <console>:29: error: Rating.type does not take parameters Rating(fields(0).toInt, fields(1).toInt, fields(2).toFloat, fields(3).toLong) ^ In standard scala repl, it has the same error. Scala/spark-shell repl has some quirks (e.g. packages are also not well supported). The reason of errors is that scala/spark-shell repl discards previous definitions when we define the Object with the same class name. Solution: We can rename the Object Rating. ## How was this patch tested? (Please explain how this patch was tested.

| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | ## 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?

* [MINOR] Remove inappropriate type notation and extra anonymous closure ↵hyukjinkwon2016-04-163-8/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | within functional transformations ## What changes were proposed in this pull request? This PR removes - Inappropriate type notations For example, from ```scala words.foreachRDD { (rdd: RDD[String], time: Time) => ... ``` to ```scala words.foreachRDD { (rdd, time) => ... ``` - Extra anonymous closure within functional transformations. For example, ```scala .map(item => { ... }) ``` which can be just simply as below: ```scala .map { item => ... } ``` and corrects some obvious style nits. ## How was this patch tested? This was tested after adding rules in `scalastyle-config.xml`, which ended up with not finding all perfectly. The rules applied were below: - For the first correction, ```xml <check customId="NoExtraClosure" level="error" class="org.scalastyle.file.RegexChecker" enabled="true"> <parameters><parameter name="regex">(?m)\.[a-zA-Z_][a-zA-Z0-9]*\(\s*[^,]+s*=>\s*\{[^\}]+\}\s*\)</parameter></parameters> </check> ``` ```xml <check customId="NoExtraClosure" level="error" class="org.scalastyle.file.RegexChecker" enabled="true"> <parameters><parameter name="regex">\.[a-zA-Z_][a-zA-Z0-9]*\s*[\{|\(]([^\n>,]+=>)?\s*\{([^()]|(?R))*\}^[,]</parameter></parameters> </check> ``` - For the second correction ```xml <check customId="TypeNotation" level="error" class="org.scalastyle.file.RegexChecker" enabled="true"> <parameters><parameter name="regex">\.[a-zA-Z_][a-zA-Z0-9]*\s*[\{|\(]\s*\([^):]*:R))*\}^[,]</parameter></parameters> </check> ``` **Those rules were not added** Author: hyukjinkwon <gurwls223@gmail.com> Closes #12413 from HyukjinKwon/SPARK-style.

According to the [Spark Code Style Guide](https://cwiki.apache.org/confluence/display/SPARK/Spark+Code+Style+Guide) and [Scala Style Guide](http://docs.scala-lang.org/style/control-structures.html#curlybraces), we had better enforce the following rule. ``` case: Always omit braces in case clauses. ``` This PR makes a new ScalaStyle rule, 'OmitBracesInCase', and enforces it to the code. ## How was this patch tested?
