Jobid creation is not required if the job failed because of unavailability of
input path.Can input and output paths validation can be done before job ID
creation step?

Key: MAPREDUCE-4130
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4130
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mrv2
Reporter: Ramgopal N
Priority: Minor
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
