Jesse Anderson created HADOOP-12271:
---------------------------------------

             Summary: Hadoop Jar Error Should Be More Explanatory
                 Key: HADOOP-12271
                 URL: https://issues.apache.org/jira/browse/HADOOP-12271
             Project: Hadoop Common
          Issue Type: Improvement
            Reporter: Jesse Anderson
            Priority: Minor


When the "hadoop jar" command is used and the JAR does not exist, the error message says "Not a valid JAR: ...". The message should say that the JAR does not exist. This error makes it sound like the JAR is corrupt or is not a JAR format.
