To rerun a job, enter the following command:
rerun --log_dir=l_d --job=Ff::Jj
where l_d is the log directory and Ff is the family name and Jj is the job name.
If you run the command like this:
rerun --log_dir=l_d --job=Ff::Jj \
--cascade --family_dir=f_d
then all the jobs that are directly or indirectly dependent on job Jj in family Ff will also be rerun.
If you run the command like this:
rerun --log_dir=l_d --job=Ff::Jj \
--dependents_only --family_dir=f_d
then only those jobs that are directly or indirectly dependent on job Jj in family Ff will be rerun. Job Jj will be unaffected.
You can use the "Rerun" button on the 'Status' or 'View Logs' page.
