>                 Key: HADOOP-1971
>                 URL: https://issues.apache.org/jira/browse/HADOOP-1971
>             Project: Hadoop
>          Issue Type: Bug
>          Components: mapred
>    Affects Versions: 0.13.1
>         Environment: Centos, java 1.5
>            Reporter: Ted Dunning
>            Assignee: Enis Soztutar
>            Priority: Minor
>
> If this line from a typical map/reduce program
>         JobConf conf = new JobConf(Flatten.class);
> has the argument deleted then I get a message that the input format that I specify cannot be found.  That message leads a naive user on a rat chase.  I only corrected this by bisecting against a working program.
