Hadoop

                 Key: HADOOP-897
                 URL: https://issues.apache.org/jira/browse/HADOOP-897
             Project: Hadoop
          Issue Type: Improvement
          Components: build
    Affects Versions: 0.10.1
         Environment: All
            Reporter: Milind Bhandarkar
         Assigned To: Milind Bhandarkar
            Priority: Minor
             Fix For: 0.11.0
         Attachments: compiler-args.patch

Currently, if one has to specify arbitrary command-line options, such as 
"-Xlint:unchecked", to javac, one has to edit build.xml. There should be a 
property, javac.args, that can be specified on the ant command-line, as follows:

ant compile -Djavac.args="-Xlint:unchecked"

Patch forthcoming.
