             Summary: Eliminate unused imports checkstyle warnings
                 Key: YARN-5239
                 URL: https://issues.apache.org/jira/browse/YARN-5239
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: timelineserver
    Affects Versions: YARN-2928
            Reporter: Joep Rottinghuis
            Assignee: Joep Rottinghuis
            Priority: Trivial


There are ~8 existing checkstyle issues generated due to unused imports.
By fully qualifying the classes in javadoc and manually wrapping the javadoc under 80 characters we can eliminate these warnings.
This will help with the eventual merge because then we introduce 8 fewer checkstyle warnings.

The only checkstyle warnings left are now too many arguments, which cannot be easily refactored w/o changing code structure.
