                 Key: HADOOP-2082
                 URL: htt
ps://issues.apache.org/jira/browse/HADOOP-2082
             Project: Hadoop
          Issue Type: Improvement
            Reporter: Owen O'Malley


A user was moving from 0.13 to 0.14 and was invoking
randomwriter with a config on the command line like:

bin/hadoop jar hadoop-*-examples.jar randomwriter output
conf.xml

which worked in 0.13, but in 0.14 it ignores the conf.xml
without complaining. The equivalent is 

bin/hadoop jar hadoop-*-examples.jar randomwriter -conf
conf.xml output
