+  Checkstyle configuration for Hadoop that is based on the sun_checks.xml file
+  that is bundled with Checkstyle and includes checks for:
+
+    - the Java Language Specification at
+      http://java.sun.com/docs/books/jls/second_edition/html/index.html
+
+    - the Sun Code Conventions at http://java.sun.com/docs/codeconv/

+
+    - the JDK Api documentation http://java.sun.com/j2se/docs/api/index.html
+
+    - some best practices
+
+  Checkstyle is very configurable. Be sure to read the documentation at
+  http://checkstyle.sf.net (or in your downloaded distribution).
+
+  Most Checks are configurable, be sure to consult the documentation.
+
+  To completely disable a check, just comment it out or delete it from the file.
+
+  Finally, it is worth reading the documentation.

-
-  Checkstyle configuration for Hadoop that is based on the sun_checks.xml file
-  that is bundled with Checkstyle and includes checks for:
-
-    - the Java Language Specification at
-      http://java.sun.com/docs/books/jls/second_edition/html/index.html
-
-    - the Sun Code Conventions at http://java.sun.com/docs/codeconv/
-
-    - the Javadoc guidelines at
-      http://java.sun.com/j2se/javadoc/writingdoccomments/index.html
-
-    - the JDK Api documentation http://java.sun.com/j2se/docs/api/index.html
-
-    - some best practices
-
-  Checkstyle is very configurable. Be sure to read the documentation at
-  http://checkstyle.sf.net (or in your downloaded distribution).
-
-  Most Checks are configurable, be sure to consult the documentation.
-
-  To completely disable a check, just comment it out or delete it from the file.
-
-  Finally, it is worth reading the documentation.

-
-  Checkstyle configuration for Hadoop that is based on the sun_checks.xml file
-  that is bundled with Checkstyle and includes checks for:
-
-    - the Java Language Specification at
-      http://java.sun.com/docs/books/jls/second_edition/html/index.html
-
-    - the Sun Code Conventions at http://java.sun.com/docs/codeconv/
-
-    - the Javadoc guidelines at
-      http://java.sun.com/j2se/javadoc/writingdoccomments/index.html
-
-    - the JDK Api documentation http://java.sun.com/j2se/docs/api/index.html
-
-    - some best practices
-
-  Checkstyle is very configurable. Be sure to read the documentation at
-  http://checkstyle.sf.net (or in your downloaded distribution).
-
-  Most Checks are configurable, be sure to consult the documentation.
-
-  To completely disable a check, just comment it out or delete it from the file.
-
-  Finally, it is worth reading the documentation.
