[SPARK-14868] Enable NewLineAtEofChecker in checkstyle and fix lint-java errors ## What changes were proposed in this pull request? Spark uses `NewLineAtEofChecker` rule in Scala by ScalaStyle. And, most Java code also comply with the rule. This PR aims to enforce the same rule `NewlineAtEndOfFile` by CheckStyle explicitly. Also, this fixes lint-java errors since SPARK-14465. The followings are the items. - Adds a new line at the end of the files (19 files) - Fixes 25 lint-java errors (12 RedundantModifier, 6 **ArrayTypeStyle**, 2 LineLength, 2 UnusedImports, 2 RegexpSingleline, 1 ModifierOrder) ## How was this patch tested? After the Jenkins test succeeds, `dev/lint-java` shows no errors. (Currently, Jenkins dose not run lint-java.) ```bash $ dev/lint-java Using `mvn` from path: /usr/local/bin/mvn Checkstyle checks passed. ``` You can merge this pull request into a Git repository by running: $ git pull https://github.com/dongjoon-hyun/spark SPARK-14868 Alternatively you can review and apply these changes as the patch at: https://github.com/apache/spark/pull/12632.patch To close this pull request, make a commit to your master/trunk branch with (at least) the following in the commit message: This closes #12632 ---- commit d20e16764c4ae4e7a645df3db650b9872a075eda Author: Dongjoon Hyun <dongj...@apache.org> Date: 2016-04-23T05:56:31Z [SPARK-14868] Enable NewLineAtEofChecker in checkstyle and fix lint-java errors ---- --- If your project is set up for it, you can reply to this email and have your reply appear on GitHub as well.
