Description

If the input splits cannot be computed because the input paths doesnt exist
Job is not submitted and error is thrown.But before that jobid is created which can be avoided.
The sequence is
1)Output path validation
2)Jobid creation
3)Input splits computation

But if the sequence of steps is 1,3,2 ...unnecessary jobid creation can be avoided
