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This type of job termination occurs when a restarted job uses a checkpoint file that is either out-of-date or that was created by another job.
Solution:
To avoid this problem, only submit jobs with unique, specified job names.
For more information about checkpoint restarting, see “Teradata PT Features” in Teradata Parallel Transporter Reference.
