Currently, DistCp has an > -update option for overwriting dst files if src is different from dst. > However, it is not enough for sync. If there are some files in dst but not > exist in src, there is no easy way to delete them. We should add a new > option, say -delete, so that DistCp will delete the non-existing in dst. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
