|
| 25 | + Checkstyle configuration for Hadoop that is based on the sun_checks.xml file |
| 26 | + that is bundled with Checkstyle and includes checks for: |
| 27 | +
|
| 28 | + - the Java Language Specification at |
| 29 | + http://java.sun.com/docs/books/jls/second_edition/html/index.html |
| 30 | +
|
| 31 | + - the Sun Code Conventions at http://java.sun.com/docs/codeconv/ |
| 32 | +
|
| 33 | + - the Javadoc guidelines at |
| 34 | + http://java.sun.com/j2se/javadoc/writingdoccomments/index.html |
| 35 | +
|
| 36 | + - the JDK Api documentation http://java.sun.com/j2se/docs/api/index.html |
| 37 | +
|
| 38 | + - some best practices |
| 39 | +
|
| 40 | + Checkstyle is very configurable. Be sure to read the documentation at |
| 41 | + http://checkstyle.sf.net (or in your downloaded distribution). |
| 42 | +
|
| 43 | + Most Checks are configurable, be sure to consult the documentation. |
| 44 | +
|
| 45 | + To completely disable a check, just comment it out or delete it from the file. |
| 46 | +
|
| 47 | + Finally, it is worth reading the documentation. |
