Restart Failures Due to Checkpoint Files
Error message: Cannot get current job step from the Checkpoint file.
This type of job termination occurs when a restarted job uses a checkpoint file that is either out-of-date or that was created by another job.
To avoid this problem, only submit jobs with unique, specified job names.
For more information about checkpoint restarting, see “Teradata PT Features” in the Teradata Parallel Transporter Reference.
