What changes were proposed in this pull request?\r\n\r\nThis PR removes \r\n\r\n- Inappropriate type notations\r\n    For example, from\r\n    ```scala\r\n    words.foreachRDD { (rdd: RDD[String], time: Time) =>\r\n    ...\r\n    ```\r\n    to\r\n    ```scala\r\n    words.foreachRDD { (rdd, time) => \r\n    ...\r\n    ```\r\n\r\n- Extra anonymous closure within functional transformations.\r\n    For example,\r\n    ```scala\r\n    .map(item => {\r\n      ...\r\n    })\r\n    ```\r\n\r\n    which can be just simply as below:\r\n\r\n    ```scala\r\n    .map { item => \r\n      ...\r\n    }\r\n    ```\r\n\r\nand corrects some obvious style nits.\r\n\r\n\r\n## How was this patch tested?\r\n\r\nThis was tested after adding rules in `scalastyle-config.xml`, which ended up with not finding all perfectly.\r\n\r\nThe rules applied were below:\r\n\r\n- For the first correction,\r\n\r\n```xml\r\n<check customId=\"NoExtraClosure\" level=\"error\" class=\"org.scalastyle.file.RegexChecker\" enabled=\"true\">\r\n    <parameters><parameter name=\"regex\">(?m)\\.[a-zA-Z_][a-zA-Z0-9]*\\(\\s*[^,]+s*=>\\s*\\{[^\\}]+\\}\\s*\\)</parameter></parameters>\r\n</check>\r\n```\r\n\r\n```xml\r\n<check

customId=\"TypeNotation\" level=\"error\" class=\"org.scalastyle.file.RegexChecker\" enabled=\"true\">\r\n    <parameters><parameter name=\"regex\">\\.[a-zA-Z_][a-zA-Z0-9]*\\s*[\\{|\\(]\\s*\\([^):]*:R))*\\}^[,]</parameter></parameters>\r\n</check>\r\n```\r\n\r\n**Those rules were not
