How to Reset Kafka Consumer Group Offset

Kafka 0.11.0.0 (Confluent 3.3.0) added support to manipulate offsets for a consumer group via cli kafka-consumer-groups command.

  1. List the topics to which the group is subscribed
kafka-consumer-groups --bootstrap-server <kafkahost:port> --group <group_id> --describe

Note the values under "CURRENT-OFFSET" and "LOG-END-OFFSET". "CURRENT-OFFSET" is the offset where this consumer group is currently at in each of the partitions.

  1. Reset the consumer offset for a topic (preview)

Random delay for cron.daily, cron.weekly, cron.monthly

Wouldn’t it be nice if cron’s daily, weekly and monthly jobs could be run with a
slight offset? At least that’s what I thought when 20+ servers were hitting my
backup infrastructure at once. The scripts in /etc/cron.daily,
/etc/cron.weekly and /etc/cron.monthly are triggered directly from crontab
at fixed times. Here’s what /etc/crontab looks like in Ubuntu Server 16.04:
