> JobSubmitter#checkSpecs doesn not judge whether reduceNums is less than zero.
> {code:java}
> private void checkSpecs(Job job) throws ClassNotFoundException,
> InterruptedException, IOException {
> JobConf jConf = (JobConf)job.getConfiguration();
> // Check the output specification

> } else {
> jConf.getOutputFormat().checkOutputSpecs(jtFs, jConf);

> {code}
> The code does handle the situation when reduceTaskNums is set to -1 or any
> other value less than zero.
> When use hive, the "mapred.reduce.tasks" has a default value -1.
