i using cron job schedule shell script after every 2 minutes containing pig , hive scripts. want know how fault tolerant cron job is, suppose if network goes down or file getting corrupted when job running, cron job gonna ? going restart shell script again or happen. not getting info on over internet. b great if guys help. thanks

oozie uses dag , checks data availability when multiple scripts launched share it. oozie allows work easier dependencies pig , hive jobs. integrated yarn less afraid of blowing cluster.

if data corrupted cron nothing, wait next execution cycle. might fill que easy cron might lead jobs being executed longer.
